This is part of Shinzi Katoh's "ringo" series. "Ringo" means "apple" in Japanese.
There are 2 little apple bottles and one little "suction" piece that allows you to transfer the soy sauce from the bottle to one of the little bottles. This is a cute way to take sauce with you for lunch!
Each bottle holds 4ml. The temperature range is -20~80 degrees Celsius. I would wash these by hand.
