Is there a repeating rule in size or shape when HASAMI PORCELAIN tableware items are placed together?

When examining tableware from HASAMI PORCELAIN, the same width of 8.5cm diameter stands out first across mugs, tumblers, and plates. Since its founding, the brand has consistently maintained its unique materials and cylindrical modular standards across its signature product lines^[1].

For example, a tumbler with an 8.5cm diameter and a height of 10.6cm can be used with a Plate 85 or Wood Tray 85 of the same specification placed on top as a lid^[2][3]. Mugs also share the same opening diameter across all three sizes, allowing them to be neatly stacked on top of each other, and a Plate 85 or Wood Plate 85 can be utilized as a lid to block dust^[4][5].

Because rim dimensions are matched even among vessels with different uses, space can be saved by stacking them neatly for storage, and small plates can be easily repurposed as covers or saucers when drinking tea or coffee.
