I purchased this at the store yesterday. This is only for the large pouch from the mikko 3-piece pouch set! Please note that this is only for the large pouch as shown in the photo! Size: Approximately 26.5 x 20.8 cm. There is no gusset. This is a large pouch. I think you can put a lot of cosmetics in it, and it's also a great size for organizing your travel items. If you remake a shoulder strap, I think it's a size that can also be used as a sacoche. I only wanted the small size, so I'm selling the rest. How about it for those who only wanted the large size? As in the first photo, I immediately disassembled it and put it back in the original bag. I took the photos and put it back immediately. I haven't touched it much, but as far as I can see, there are no stains, but I would appreciate it if you could understand initial scratches, etc. It's a soft item, so it will be shipped in a vinyl package only, not with bubble wrap, and will be shipped via Yu-packet Post. Please understand. As you can see in the 4th and 5th photos, there are some wrinkles from the beginning. If you don't mind, or if you're okay with lightly ironing it, I would appreciate it.
