Not sure what else I can say about this. 😂 Zipper totally functional, no sticking. Ring with the little chain can give you the option of attaching to a purse, zipper, bag, etc! No marks- anything that looks like a mark is a shadow on the piece because it’s super difficult to photograph this thing… I don’t think this came with the dust bag but it fits so you’re getting that too. 😂 Measures approximate: 4.25” wide 3” high Opens to 2.75” at the widest but obviously you couldn’t zip it closed at that. Smoke/pet free home! Let me know if you need additional pictures or measurements. 😊
