Tea-ware and tableware lids generally have a plain surface, but by creating “clump” shaped lids giving each its own role, a tableware collection with a single stone seemingly stacked on was created.

An iron kettle and a teapot for Chinese tea, both with a lid made of hollow silicon, the addition of multiple holes on one side, the lid enabled it to function as a tea strainer and keep loose tea leaves inside.By incorporating a similar lid for a glass water jug, it became possible to use it for cold brewing tea. In addition, for high heat retention the lid of the Chinese tea cup was made out of urethane foam with consideration to prevent the cups from making unpleasant “clatter” when placed on a table.Both lids have very low thermal conductivity, so the heat will not be a problem when touched directly by hand.Similar expressions were also developed on square, round and long plates.
The square and long plates, appear to have partially sunken expressions depending on the weight of the accompanying stone. These stones may also function as small pots and can be used by pouring sauces inside.For the round plates, the stone is sunken into the central part, sauces may accumulate further emphasizing the stone and resulting in an independent appearance.

The coffee pot, mugs, coffee dripper, milk jug and sugar bowl, all have a “stacked stones” design which may be used as is. For the coffee pot and mugs a stone-type dripper can be used instead of a lid, it is also possible to stack and carry the milk jug or the sugar bowl on the pot.
