It feels like jersey material (˃̵ᴗ˂̵) The design on the front and back is really cool ☆ The left knee area is a little dirty, but it's not very noticeable! There's some pilling on the ribbed parts of the wrists, ankles, hem, and waist. If you'd like, I'll try to remove them as much as possible before shipping (・̑◡・̑) I bought this in 140cm, but it seems to run a little small, so it might fit a child who wears 130cm perfectly!!
