This is a set of 4 DS Card Blocks, specifically designed for Nintendo DS game cards. Originally, there were 6, but this is a listing for only 4. These are convenient for carrying DS cards, as they can be connected like building blocks. They haven't been used much, but the purple case has some minor scratches. There are also some small scratches visible when held up to the light. I'm looking for buyers who aren't too concerned about these minor imperfections and who understand that these items have been stored for a long time.
