Immediate purchase is OK. This is Daiso's all-purpose wrap lid. It's a lid that you place on a dish instead of plastic wrap. ⚠️ Cannot be used in an oven. Daiso sells them in sets of one large and one small, but I wanted the large ones and have plenty of small ones, so I'm selling the ones I don't need. Out of the 6 pieces, 1 has been used but washed. 《Size》 Diameter: 13.4cm Inner diameter: 12.9cm Please note that these are amateur measurements and may have some errors. 《To ⑦, Photo ⑤》
