Bandori Dororis rubber strap. After opening, it was placed in a sleeve and stored in a dark place. I will take measures to prevent water damage with an OPP bag. If you wish, I will wrap it with bubble wrap. Please let me know in the comments or after completing your purchase. If you have any other questions, please comment! ---Search Keywords--- BanG Dream!
