This is a Kogitsunemaru rubber strap from the Touken Ranbu Koedarize R Rubber Strap Collection. I have kept it carefully since I bought it. New and unopened. I decided to sell it due to decluttering. I don't plan to include the box, but if you want it, I will fold it and ship it, so please let me know in the comments. If you purchase it with other items, I may be able to offer a small discount, so please let me know in the comments.
