Spot the "shower cap" on the plate? I found a kitchen item called "food cover" that can be washed and used many times at the 100-yen shop CAN DO.
Goods for covering plates and cups containing food. One set consists of three sizes: "Large (approx. 20 cm in diameter)", "Medium (approx. 13.5 cm in diameter)", and "Small (approx. 10.5 cm in diameter)". Since it can be expanded and contracted with rubber like a shower cap, it can be used for tableware of various sizes. You can put it on instantly.
All sizes have loops, so you can hang them on hooks after washing. If you hang it on the side of a refrigerator or cupboard, you can easily use it every day.
It is regrettable that it is not compatible with microwave ovens, but it is a hood cover that can be easily covered to reduce the disposable wrap. Why don't you feel free to give it a try? The price is, of course, 108 yen (tax included).
