This is a disc storage case for CDs/DVDs, etc. It's made of sturdy silver metal. It's a 6-hole ring binder type. The top and bottom cases are the same, with only the pattern of the non-woven fabric files for holding the discs being different. I haven't used them much, but there are some minor scratches from storage. It can hold 12 discs. I will ship it via Nekopos.
