I purchased this about a year and a half ago. I don't think there are any noticeable stains or dirt as I've only used it a few times. I think there is some deterioration over time, so please check the images carefully and purchase with your understanding. It will be shipped folded up small. Instant purchase is welcome. Quoted from the official website: This cute tent-shaped mug case is perfect! Of course, it fits MagMags, and its cute, round shape also makes it a great baby snack pouch. ■Quality indication Surface laminate processing, polyester, cotton, nylon ■Size Height 17, circumference 39.5, diameter 12, handle 18 (all units are cm)
