These are patterned pants from "Inai Inai Baa!" featuring U-tan. The inside is fleece, so it looks fluffy and warm. I don't see any noticeable stains, but this is a used item and I am a private seller, so please understand that there may be oversights before purchasing. The number of days until shipping may be moved up. Also, the shipping method may be changed from Yu-Yu Mercari Bin to Raku-Raku Mercari Bin or vice versa without notice. *I have a cat. I take as much care as possible, but it's not perfect. Please understand this as well.
