DESIGN NAME: Tsutsumu
PRIMARY FUNCTION: Business Card Holder
INSPIRATION: Tsutsumu Card Case was brought to life based on the Japanese custom of wrapping valued items carefully, such as "furoshiki (a large piece of cloth used to wrap objects)," "noshibukuro (a special envelope used for gifts of money)" and "fukusa (a square piece of cloth used to wrap the noshibukuro)." It is made by folding a piece of high-quality leather - beautifully, like origami - without using a single piece of fastening material. TSUTUMU is designed to gently wrap your valuable business cards.
UNIQUE PROPERTIES / PROJECT DESCRIPTION: Card cases that do not use stitches or hardware at all, as long as they are investigated, do not exist in the market. Usually, we use thin leather for the card case. Tsutsumu is also characterized by a very compact size despite the use of thick leather.
And it is a symmetry and extremely simple design.
OPERATION / FLOW / INTERACTION: A semicircular cutout can be felt under the cover without looking, so you can quickly and smoothly remove your card from the case without looking down.

PRODUCTION / REALIZATION TECHNOLOGY: Simple design seems easy at first glance, but it is very difficult to complete.
No glue, no stitches, no rivets.Without using any stitches or hardware, it was difficult to make shape by just folding leather.
In order to realize this design like "origami", we needed to find a leather with suitable characteristics.
At last, We found best one, Italian Vachetta Leather (Elbamatt, Tempesti, Toscana).
The soft and pleasant texture of the leather becomes better and richer as it ages. It is a palm-size masterpiece that looks stylish in business situations while also expressing users' elegance.

RESEARCH ABSTRACT: Vegetable tanning is a tanning process taking inspiration from nature and - in full harmony - to nature going back.Vegetable-tanned leather does not contain any toxic substance harmful to man and is highly tolerable for those who suffer from metal related allergies.Vegetable-tanned leather productive cycle is strictly monitored to ensure a low impact on the environment.
No animal is killed for its skin. On the contrary, the raw hides used for Tsutsumu are the discarded by-products of the food industry producing meat for human consumption.
CHALLENGE: Without using any stitches or hardware, it was difficult to make shape by just folding leather.
In order to realize this design like "origami", We developed our own design.Wrap the business card with three flaps, the top one is just a cover.
Since there are no hardware, you can open and close the cover without any stress.
