Adjustable-size cup sleeves. I have too many, so I'm selling them. The insertion opening can be adjusted to three sizes: S, M, and L (approximately 7-14 ounces). Wrap it around a paper cup to prevent direct heat transfer and make it easier to hold. Made of paper craft paper with a simple and stylish design. If you purchase 300 pieces, it's usually 3,000 yen, but I'll sell them for 2,500 yen (including shipping), so please comment.
