★ Tupperware one-touch canisters. ★ The seals are A&B, so I think they are SS & S sizes. ★ These are convenient canisters that snap shut when you press the center. ★ They were useful for separating and pickling a small amount of plums that were culled from a large batch, as you could see the contents. ★ For those who want to start with a small amount of plum syrup, pickled plums, miso, etc... ★ Although I don't see any major damage, there are some scratches and signs of use, and the scent of plums remains. Please understand. ★ I used them this year and had no problems. ★ I am also selling unused toppers canisters (green seal, plain). ★ Please understand that these are used items, sold by an individual, and stored at home before making a purchase.
