Very cool looking tshirt! 65% Polyester, 35% cotton. Don't want to wear a costume and don't want to get in Paul Stanley shape, then this is the alternative. Backside is printed like the backside of the Starchild's costume also. These shirts are sublimated. Sublimation is the process of transferring dye to a fabric using heat. The images and graphics are printed on special paper placed on the garment and heat is applied, allowing the ink to become part of the fabric. These will be lighter than photo shows due to this process. These are officially licensed.
