Holds 12 3DS game cartridges. I was using it to store games until recently. There are scratches and scuffs on the outside, and the scratches are noticeable when light hits them. Please check the photos. There is no problem with storing the cards, but please be aware of this if you are concerned. I love Pokémon and have treasured this item, so I would like to sell it to someone who needs it. This item has been stored at home for a long time. Please understand this before purchasing, and please refrain from returns or claims. ★ If you purchase other items together, we may be able to offer a discount, so please feel free to consult with us in the comments.
