Marble gray silicone ice cube tray set of 3, capable of creating ice in various shapes. Approximately 10 cm square. Thank you for looking. I purchased these to freeze small portions of dashi, fresh cream, leftover tomato sauce, etc., but I don't use them often, so I'm selling them to organize. I've used them about 2 or 3 times. The top one is the lid. I plan to use Yu-Packet Plus for shipping.
