By expanding the potential of box furniture technology cultivated in Tokushima, we developed a rectangular mirror with casters, together with the planner, manufacturer, and seller Akizuki Mokko. FRAMES was initially a flat (2D) mirror, which developed into a rectangular solid (3D). As it is hollow inside, we were able to hide storage space and casters that would be usually visible. For this reason, it can be in boutiques where space is limited, used by up to 4 people at one time. For the use in various types of boutiques and salons, we pursued a simple shape. The 8 mm frame seems thinner than it looks, as the thickness of the outer frame of the mirror is inside―a unique technique of Tokushima's artisans.
