This is a Hello Kitty New Year's money envelope (pochibukuro). It comes with stickers. It seems that 3 were used, but the remaining 5 have been kept unused. Since they are quite old, the back side seems to be slightly discolored. I don't think there are any noticeable stains, but please consider that these are used items and have been stored at home for a long time. ❖ They will be simply packaged and sent by post. ❖ Packaging materials may be recycled. ❖ There are no pets or smokers.
