Long-sleeved T-shirt set with dinosaur pattern and stripe design. - Design: Dinosaur pattern - Colors: Gray, Green, Black, White - Material: Cotton - Style: Long sleeve - Pattern: Stripes, Camouflage Thank you for viewing. This is a set of four long-sleeved T-shirts purchased at Costco. One of them has a button design on the back. There were two small stains, but otherwise, the condition is relatively good. The size is indicated as 12M, and I used to dress my child in them when they were wearing clothes around 80cm.
