Purchased at the bobochoses store. I wore them frequently because I liked them, so they have a fair amount of wear, but there are no stains or tears. The size is listed as 26-28, which is approximately 16.5-17.5cm in Japanese sizes. They run a little small. I will also include a car-patterned children's mask as a bonus, which I received as a special gift when I purchased them. However, please understand that they were worn by a child.
