Why are we doing?

Auto-translated
Show original
Proposals for making products made in Japan that are not bound by the "how" of the industry. I want to change the inconvenience that I have been thinking about since I was a professional athlete who flies around the world to be convenient. We need specialized products, but we want to reduce the "waste" that can only be used at that time.

What are we doing?

We propose items that can be customized according to various situations such as small outings, travel, outdoor leisure, etc.
 
The fun of combining and choosing, the Cinderella fit in which the items in the brand are linked, and we propose outing items that realize a smart and comfortable one-action by carrying lighter and thinner luggage
 
 
Of course, it can be used by both men and women
 
 
 

Commitment to the product

Since the items attached to the sash cord can be customized, items that need to be carried around in everyday use (smartphones, wallets, cards, earphones, keys, etc.) can be taken at a high speed while enabling second-to-second action [not dropped, not forgotten, not lost].
 
While each product has functionality, it is not only easy to use casually for both men and women, but also has functions and responsiveness that can be used not only for everyday use but also for many situations such as hobbies, sports, and work.

Who are supporting us?

I would like to use it for men and women in their 30s to 60s who are active and like to play outside, such as going out, playing outside, and traveling.
