Two long-sleeved dinosaur-patterned undershirts/inner shirts are being sold as a set. The material is 100% cotton, so I think it will be comfortable to wear. They have been washed, but there are stains that could not be removed. (Photos 8 and 9) The tag has a name written on it, which has been blacked out. (Photos 4 and 11) Please understand that these are used items before purchasing.
