【Washi Paper Type】 The plain ones use five colors of washi paper for a soft finish. The patterned ones use chiyogami (patterned washi paper) with floral designs. Size: 7.5cm. They are disposable, but they last quite a while since you can use them until they get dirty. At home, I made one using regular origami paper and 100-yen store chiyogami, and I've been using it for about a month. It seems they last a long time if you use them carefully. I think customers would be happy to use them as coasters for tea (^-^) I think they would also be a good gift for foreigners (•‿•) I'm looking for buyers who can provide some comments after purchase.
