Largely inspired by stack a ring toy, Jimmy owns the feature of multiple layers stacking with each other. It functions as a stationery tower in the context of home office. It is made of 2 display trays and a storage unit stacking through a pivot. Depressions on the trays are cut using CNC machine according to the outline of standard stationery. By removing the top cap, the display trays are able to be taken out as table management objects.
