This is a pouch with a strap, exclusive to Da-iCE fan club members. The pouch is approximately 10 x 16 cm in size. The strap is brand new and unused, but the pouch has been used a few times. Upon close inspection, the silver print appears to be slightly peeling, as shown in the second photo. I believe this was a very old fan club item, from around the first or second year of Da-iCE's major debut. It's no longer available.
