B.O.
（FUJIEI, 2019）
A chair that will open your mind like a bottle opener, and create a bright space. In fact, the wide-opened unique hole on the back is designed to reduce the oppressiveness to the space, and present a lively scene when a large number is installed.
On the occasion of the development of the item, in order to consider the design of the shell and prepare for the presentation, the designer himself made the original mold for an actually-working bottle opener of brass under the instructions of a metal casting artist.
