This is a set of two adidas t-shirts. The right one is 140cm. The left one has had the tag cut off, so I'm not sure, but it's the same size as the right t-shirt, so I think it's either 140 or around 130. Both were used by a child. The right one is cotton, and the left one is made of a smooth, quick-drying fabric. They are in good condition, but they are used, so please understand this before purchasing.
