I was collecting these, but I've run out of space, so I'm putting them up for sale. They were also new and unused when I purchased them on Mercari, and I haven't used them either, as I've kept them at home. There are some remaining marks from the sticker removal on the bottom of the cups. Please check the photos. I think they are relatively clean, but please refrain from purchasing if you have any concerns, as they have been stored at home. Thank you for your understanding and purchase.
