About this project
New Color Launching. We just add 5 new colors into our TAKUMI Pen. Limited Quantity! Please click HERE or the above picture for more information. While we are appreciated our goal passed 200%. There are nothing but to say a big THANKS to everyone.
Thanks for all your support!!!
We are really excited to launch our first project!
The TAKUMI Pen is the first length adjustable pen in the world.
Accepting over 50 different ink refills and with the ability to adjust the length of the pen body, you can finally build a pen that fits your own style and comfort level!
We have spent over 5 months on the design and development process for this project, making many modifications as we went—all in order to bring you the most versatile pen in the world!
The ink pen is probably the most ubiquitous communication tool in all of human history. Not long ago, people didn’t have the many communication methods that we do now (computers, smart phones, text messaging, the Internet, etc.).
For centuries and in many different forms, the pen has played a crucial role so people could visualize their thinking and document information. Nowadays, even though we have so many options and products to help us communicate, the mighty pen is still an irreplaceable item in our pocket or purse and on our desk. It is tiny but cannot be ignored; you will always need a pen handy throughout the day, and at just the right moment.
For all these reasons and more, we proudly introduce the TAKUMI Pen!
Have you ever fallen in love with a pen’s refill or ink or the way it flows onto the paper, but the pen’s body doesn’t fit your hand or you don’t like the overall design? Maybe it’s too bulky; maybe its grip is too “bumpy”; maybe it’s not stylish enough for your refined tastes.
Although the current stationery market provides numerous pen choices, there seem to be some things that are missing: missing taste; missing ergonomics; missing thoughtfulness; and above all, most of today’s pens lack quality, reliability, and STYLE. Therefore, we decided to make the most adaptable and stylish pen in the world that allows YOU to choose your favorite refills and still keep the style and ergonomics you love.
Even though most people know how to hold a pen, different people hold their pens in many different ways and positions.
The problem is, it isn’t always easy to find a quality writing instrument that fit all of the various hands and holding techniques of different people. We have painstakingly designed the perfect solution with our TAKUMI Pen!
One key feature of our unique pen is that it is conveniently adjustable to fit everyone’s hand, writing position, and usage—from note-taking to manuscripts; technical drawing to sketching & shading; and all other uses you can think of. The mechanical design of the pen is modular—allowing you to interchange parts and adjust the head length to suit your individual needs.
The TAKUMI Pen helps designers sketch more smoothly by fitting the pen more comfortably to the hand. With the flexibility afforded by its adjustable head length, it can also help architects and engineers draw more precisely.
You can adjust TAKUMI's head position for over 5-15mm difference to most comfortable way to hold our pen. Moreover, you can enjoy your writing or drawing experience without touching any uncomfortable or bumpy surface simply by grasping TAKUMI's sleek, silky shaft.
Minimalism is the spirit of the overall design of the TAKUMI Pen. We use a simple, cylindrical shape to provide the most comfortable and ergonomic experience.
We tested tons of pens on the market and decided that perfect balance was essential to make the TAKUMI Pen the best of writing instruments. After extensive prototype testing, we know you will love the exquisite balance of your TAKUMI pen. In fact, you may find yourself unable to stop twirling it on your fingers as you brainstorm!
Whenever you need to sign that important contract, you really don’t want to whip out a cheap, plastic pen—no matter how well you like the way it writes or how it feels! Put that pen’s refill in the TAKUMI Pen and see for yourself how your clients will react to this exquisite writing implement. They will probably ask you how they can get one!
Color Mix with different caps also show different styles and interest for your daily use. You cannot help to keep spinning this pen on your hand with perfect weight balance.
Speaking of style, all of our parts are 100% interchangeable. Since we offer different colors and four different cap types, you can mix and match colors and cap types to create different styles for different needs. Maybe you don’t want a cap clip for your pants pocket, but need one in your suit jacket. Maybe you want a brushed silver cap with a black body. Maybe you want a black top cap and rear cap on your high-polished chrome barrel. There are virtually limitless ways you can express your own individuality and superb taste.
Machined process + Anodized treatment + Simple style = 100‘s of gorgeous ways to present your uniqueness.
All pens are portable, right? Sure, but do they all fit reliably in any pocket or purse without fear of leakage? NO! You can’t put a “click pen” in your pants pocket unless you want a pocketful of ink and a big ink-stain on your thigh! Do you wear dress or shirts? The TAKUMI Pen will not leak in your breast pocket, and it shows off your great taste and personality.
Your TAKUMI Pen with cap clips enables you to take it everywhere easily.
With the TAKUMI’s special clip design, you can clip TAKUMI on your suit, pants pocket, purse strap, travel bag—virtually anywhere!
Having discussed their favorite refills with professional pen makers and avid pen enthusiasts, we decided to make our TAKUMI Pen accept most of the refills on today’s market so you can always have what YOU consider to be the best performance with your favorite refill or refills. Our simple-yet-elegant design allows you to make hassle-free refill changes in seconds!
Do you write, draft, draw, sketch or edit? Own one TAKUMI pen for each dif-ferent need with the appropriate refill in each one for the ultimate in convenience (and mix-and-match color choices), or simply change out your favorite refills in a single TAKUMI pen for economy! The choice is yours!
For more details about refills, please check the list of known acceptable refills later in this proposal.
As for the overall design, we want to present the spirit of Minimalism. With simple and continuous circular shape, it could provide the most comfortable holding feeling. Our team test a large number of pens in the market and finally make the perfect balance for the overall dimension that makes our design ergonomically.
We provide 8 parts to assemble a full pen: shaft, head, rear cap, round cap, round cap with clip, flat cap, flat cap with clip and anti-slip tool. The combination of shaft, head ,and cap can work with multiple type of refills. Simple and smart structure to satisfy our refills-friendly and position-adjustable needs. With help from anti-slip tool, it can prevent rear cap from damaging thread during assembling.
The different top-cap styles include: round cap, round cap with clip, flat cap, and flat cap with clip. We have designed our cap clips to easily slide on or off most kinds of soft material while still adhering to the minimalist spirit behind the TAKUMI Pen. The combination of shaft, head, rear cap and top cap comprises our simple and smart structure that satisfies our multi-refill-friendly and length-adjustable design parameters.
If you really like our products and purchase multiple colors. It also looks gorgeous to mix your pen with different styles to attract other people's eyespots.
In order to show our ultimate design, one specific feature we want to present is gap-free design. With special manufacturing, we will make cap and shaft together like a continuous masterpiece. Once you open the cap, everyone surround you must be surprised to this special characteristic.
We really care about each tiny details of design, so we will fulfil this feature during the first production for the rewards you will have.
Each TAKUMI Pen is made of 7-series aluminum. This material is mainly used for aeronautics and other advanced industrial applications, and you will definitely be satisfied with its quality and durability.
Each top-cap clip is carefully crafted from high quality stainless steel to provide better elasticity and resilience.
Empty Weight: 0.8 oz (23 grams)
Length when closed: 5.7 in (145 mm)
Length when cap is posted: 5.9-6.3 in (150-160 mm)
Diameter: 0.4 in (10 mm)

In order to keep things simple and minimize fulfillment errors, the parts of each pen will all be the same color. We simply cannot mix & match the color of caps or other pieces for you—it would be a fulfillment nightmare! However, if you choose a reward or rewards of 2 pens or more, you can mix & match them yourself and create your unique style with TAKUMI.
Each of your TAKUMI pens will come packaged in an appropriately attractive, hand-stitched cover. This is just another way we show our serious commitment to superior, hand-crafted excellence.

Risks and challenges
This is our first project on Kickstarter, we didn't know how much eggort we make for this project even it is a simape stationery. However, we all use the most serious attitude to face each step for this project and hope you guys love it.
In order to provide the best outcome, we study every aspect of point that how people use their pen and make several prototypes for usage test. Over four months. In this process, we found our TAKUMI Pen samples becoming indispensable. While we would like to think that this affinity is due to superb usability, there’s always the risk of our supporters.
Even though manufacturing is always cited as the challenge as a Kickstarter project, this is actually our strength. During product development, we simultaneously conducted engineering and manufacturing work with a workshop with 20+ years of precise machining. You can rest assured that your reward shall be produced in quality and delivered like gorgeous gadgets.
The biggest challenge to us is the final marketing stage. It is our first try to the Presentation & Marketing. Moreover, we lack the budget to produce the marketing visuals that would would make this pen even better. We simply hope that you don’t judge a pen by its marketing materials. Please sponsor us to put this pen in your hand. And then you’ll agree. Thank you !Learn about accountability on Kickstarter
