This is a shoe case from Converse. I used it to hold 29cm basketball shoes, so I think it's a size that can generally fit any shoe. I'm selling it because I bought a backpack with a built-in shoe case. The opening can be closed with Velcro, but sometimes it sticks to the mesh of the main body, causing some slight fuzzing on the mesh. (This doesn't affect its use in any way.) I hope to sell it to someone who understands that it is a used item.
