I'm not sure what these are for. Small ramekin style bowl with lid. Sits in a footed coaster which can be turned over and used for a base for the bowl, or fits on top of the bowl to use like a small appetizer plate. White glazed pottery with a hand painted blue bamboo pattern and a bamboo shape finial. No marks on the bottom, but on top of each lid is a hand painted (looks like a bird in flight)detail in brown. Each is slightly different on each lid (due to being hand painted). I have 8 sets. A set consits of ramekin, lid and coaster. The elderly lady used these for spices. Each is 3" tall with lid on, plus coaster. Coaster is 3/4" tall and 4" in diameter. All are in wonderful condition with no damages or crazing.
