This is a smartphone case for the iPhone 12. I was using it on an iPhone 12 Pro, but it was bulky in my pocket, so I used it for about 3-4 days and then stored it at home. The thread ends at the seams look like they're unraveling, but they're long and I think they'll look clean if you cut them. They're not actually unraveling. It's a Dior design, but I don't know if it's authentic, but it's cute. It has a pocket that can hold one card.
