What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

"Plastics", a Japanese manufacturer, will do the Kickstarter project to create a practical storage box with enhanced design.

CA-TONとは / What's CA-TON

"CA-TON"は 、"究極なシンプルさ"を追求したプロダクトです。

"CA-TON" is a product pursuing "ultimate simplicity".


CA-TON is more resistant to humidity than cardboard and other paper products, and is made of resin with a thickness of just 0.7 mm. It is not only lightweight by a special structure (patent pending) but it is also excellent in impact resistance due to falling, collision and so on. It is designed to assemble from the folded state without using a tool, and it can be stored in a flat state when not in use. Since the main body and the lid are in a single whole piece, there is no possibility of losing or forgetting the lid.

機能美・シンプルさ / Function beauty · Simplicity


CA-TON is sticked thoroughly to the design to suit any environment.


We pursue Japan quality until the details (cut out part) of the whole atmosphere as well as course.


It’s pursued “Made in Japan” quality from the whole atmosphere down to the cut-out-part details.



Since the box has a claw on the bottom, CA-TON can be stacked beautifully and stable.

First of all, it took more than 5 times of making failed paper prototypes to confirm the structure.

In addition, we actually make the sample with the resin and check the performance.

The last point of commitment. It is the mechanism of the joint part.

An application that realizes a simple usage environment

収納物を探すとき箱を開けて中を確認しますね。 見つからなくて全ての箱を開けた、なんてよくある話しです。 CA-TONにはフタを閉じたままスマホで中身が見えるタグとアプリが付いています。 タグにお好きな文字やイラストを書きスマホをかざせば、予め登録した中身の画像を まるで透けているかのように見ることができます。

Normally you open the box and check inside as you search for stored items. You may have experienced that you open all the boxes and yet you don’t find one you are looking for. CA-TON comes with a tag and an app that allows you to see the contents in the box with the lid closed, using your smartphone. Write some words or illustrations that tell you what’s in your CA-TON on the tag, you can see the image of the contents you registered in advance as though it were transparent as long as you keep on smartphone.

 使い方はいろいろ / How to use

Easy to assemble / fold

CA-TONは折りたたまれた状態から工具を使わず組み立てが可能で、未使用時にはフラットな状態で収納できます。 本体とフタは一体構造のため、フタをなくしたり置き忘れることもありません。

CA-TON can be assembled from the folded state without using a tool, and can be stored in a flat state when not in use. Since the main body and the lid have a unitary structure, there is no possibility of losing or forgetting the lid.
