What is the product "Tsutsutsui"?

Tsutsui" is a new drinking vessel that combines "thin taste" with "tough and easy handling.

Generally speaking, the better the glass is, the more delicate it is to the palate, but many people feel that it is easy to break and difficult to use on a daily basis. Tsutsu Ii" is a new type of drinking vessel with a thin rim less than 1mm thick to enhance the taste of the beverage itself, while at the same time being "durable" enough for daily use.

The main points of realization are as follows.


The thin rim allows the flavors to develop.

Aroma of the thin-lipped shape

Practical strength that resists breakage

Compact and space-saving storage by disassembling.


The thinness of the vessel, which determines the "taste satisfaction" of home drinking, and the "ease of handling" required in modern life are compatible.

It is also possible to take the thin, delicate drinking vessel outdoors.
