This is a set of cute, afternoon tea-style, lidded, airtight ceramic storage containers, available in two sizes. They feature a silicone seal and an air hole for a perfect airtight seal, ensuring excellent functionality. Sizes: Large: Approximately 12.5cm in diameter Small: Approximately 9.5cm in diameter Height: Approximately 6cm I received these as a gift and have kept them in my cupboard without using them. Although I have never used them, there is some slight yellowing on the lids, likely due to storage. They are still perfectly usable, but please refrain from purchasing if you are concerned. Please consider this item if you understand that it has been stored at home.
