Thank you for viewing! ^_^ This item can be used both on land and in water. It looks blue in the photos, but the color is closer to emerald green. Waist: 30cm Length: 50cm Size: 150, but it runs a little small, so I've listed it as 140. There are no noticeable stains or dirt. There is some wear and tear from being worn and washed, but I think it can still be worn. Please note that the shipping method may be changed from Yu-Yu Bin to Raku-Raku Bin (or vice versa) depending on packaging and shipping timing after purchase. ※Important※ Instant purchase is welcome!
