Japanese Style Kinchaku

Bitcoin pattern

I created a traditional Japanese square drawstring bag, known as a Kinchaku, using fabric with a Bitcoin theme.
It has a square bottom and retains its square shape even when the drawstring is pulled tight.

It’s just the right size for carrying essentials like your smartphone.

Size：W 13.0 × H 17.0 × D 13.0cm (approx.)

There is a square piece of cloth at the bottom to add strength.

Product introduction

Bitcoin pattern

I created original fabric with a Bitcoin theme.
To give it a cute and playful look, I featured round items like pizza, oranges, clocks, and keys arranged in a dotted pattern.

Bitcoin puppet pattern

I have created merchandise for Spiral’s character, the Bitcoin Puppet.
Spiral is also responsible for the Lightning Development Kit (LDK) and has released characters that can be used as open source.

B.B.Bear pattern

MakingWaves’ original character, a bear (Bear) that holds (Bear) Bitcoin (Bitcoin).
It wears a traditional Japanese jinbei and engages in Bitcoin-related activities.

This character was created not for goods that prominently display Bitcoin, but for items that can be used in everyday life, with the idea of “actually being Bitcoin-related but also practical for daily use.”

＜Kinchaku＞
A bag that opens and closes by pulling on drawstrings.
It has been used in Japan for centuries and is known as a “Drawstring Bag” overseas.

Drawstring bags with a square bottom are a traditional Japanese design.
They are lightweight and can be folded compactly.
These bags pair well with traditional Japanese clothing like yukata and jinbei, and are often used to carry small items during festivals and events.
Depending on their specific design, they are sometimes referred to as Shingenbukuro.
