What's Unique about Us


We don't just sit in front of PCs and do design, but we actually make things by ourselves.
We have a workshop equipped with wood and metal machineries, CNC and 3D printers to enable the actions.

New functions often require new mechanism,
so we develop and test them over and over, to make the product come true.
New concepts are often hard to describe by words,
so we present them in REAL FORM rather than wasting too much time in meetings.

Prototyping helps people to grasp and examine new ideas, be inspired and accelerate communications.
