Thank you for viewing. This is a collaboration t-shirt between Yu Nagaba and KEEN. Not only does it feature Yu Nagaba's cute illustrations, but the fact that the character is wearing Keen sandals (UNEEK) is also a great aspect unique to this collaboration! The material is 100% cotton. I believe there are no noticeable stains. Please check the photos. Here are some rough measurements (laid flat): Shoulder width: 42.0cm Body width: 47.0cm Length: 58.0cm I am also selling a men's t-shirt from the same collaboration. Please take a look if you'd like.
