Pen Type-C is here.

Posted by cw&t (Creator)

You were the first to support us when Pen Type-A was born back in 2011. And what a journey that was. 

It's been 8 years, and we wanted you to be among the first to know about the 3rd (and likely the last) installment in the "Pen Type" series, Pen Type-C.

Pen Type-C is a minimal ultra-portable pen, precision machined out of titanium to house a high quality cartridge that never dries or leaks.

Be among the first to get a Pen Type-C :

We are sure you'll love this one.

Hi original pen type-A backers!  You may have heard already because so many of you have been on this journey with us for the last 6 years.  Thank you for tagging along!

We're back at it again. We're launching our first electronic device on Kickstarter called...

Time Since Launch

We put a lot of time and love into this project and we're on a mission to change how we think about time and timekeeping.  Help us make this a real product!

We have an early bird tier until midnight tonight (EST).

see you around!

Hi old friends,

We hope all is well in your worlds, it's been some time!

On Tuesday morning we are going to be live streaming from Preci Manufacturing in Vermont where Pen Type-A and Pen Type-B are made.

Please join us on a factory tour!

  • meet the people who work super hard every day to make your pens real 
  • check out some fancy machines 
  • get a sneak peak at some potential product releases 

The LiveStream starts at 10:30 AM EST on Tuesday Nov. 22.

Here's the link :

We hope to give you a window into the world where the pen gets made, and a sense of what our visits with our manufacturer are like. This will be super casual, and a bit ad-hoc. Hopefully it feels a bit like you're at the table with us listening in.

Please submit any questions in advance (to the live stream page) and during the stream too.

Looking forward to seeing you Tuesday!

PS We'll also have our son there with us, so be prepared for some possible toddler chaos.


Personal Body Unit Index - New Project on Kickstarter

Posted by cw&t (Creator)


Use your body to measure things!

Hope you've been having a great summer!

Today we launched a new project on Kickstarter and we wanted you to be the first to know about it.

Personal Body Unit Index is a meticulously designed poster to sharpen your internal sense of scale.


The poster features a series of diagrams of the body in 17 useful positions for measuring things which relate in scale to the human body.


We made Personal Body Unit Index to help us enhance our internal sense of scale, so we are less dependent on traditional measuring devices.


We're really excited about this new project and hope you are too.

Thanks for taking the time to read this, we really appreciate your support on projects.

Love as always,

Che-Wei + Taylor CW&T

Pen Type-B on Kickstarter

Posted by cw&t (Creator)

It’s here!!! PEN TYPE_B !!!

Hi original backers!

Thank you for coming along with us on what was a life-changing adventure when we launched Pen Type-A. It was the 6th most funded campaign on Kickstarter at the time. It completely changed our lives. We’re still a tiny studio of just 2 people and we’re still trying to make good things that we can appreciate for a long time.

Since we completed our first campaign, we got married, went back to school/work at MIT Media Lab, and had a baby boy. Right now we’re in San Francisco for 2 more months finishing an artist residency at Pier 9 (making some super fun stuff). We’ve got a serious backlog of exciting projects we’re hoping to launch in the coming months/years, so stay tuned

We are super excited to finally have Pen Type-B on Kickstarter! It’s been a long 4 years of tweaking, testing, waiting, and contemplating every detail of this pen.

This is the last pen we will EVER design.

We launched our campaign this morning, not expecting to get funded so quickly. So we’re funded...hooray! It’s happening! Still...we’ll never forget you guys and wanted to let you know about this. We’re really proud of this design, and think you’d be the ones to truly appreciate it.

If you don’t need another pen, no worries! We’ll be back with a non-pen related project soon.

We’re looking forward to sharing more adventures with you all again!
