Thank you for finding this! This is a J prize Sanemi rubber coaster from the Ichiban Kuji Demon Slayer - Proceed with an Unbreakable Heart and Blade - series. It comes with a chain, so it can also be used as a rubber strap. 〇 Product: Rubber Coaster 〇 Size: Approximately 8cm 〇 Character: Sanemi Shinazugawa 〇 Selling Method: Single item (I also have other Sanemi and Demon Slayer items for sale. Please take a look if you'd like. Also, if you purchase with other items I have listed, the shipping method and shipping cost will change, so please comment.) ★ Basically, I will ship it with the box via Yu-packet Post Mini, but if you don't need the box, I can ship it via regular mail, which will lower the price to 880 yen. If you're okay with no box, please let me know in the comments. ○ I have opened it to check the contents, but it is unused. ☆ I am also selling this on other apps, so please comment before purchasing! Instant purchase is OK. #DemonSlayer #RubberCoaster #RubberStrap #IchibanKuji #SanemiShinazugawa Type...Anime Name...Demon Slayer Title...Demon Slayer Demon Slayer/Character Name...Sanemi Shinazugawa
