Our photography backdrops are made from durable polyester fabric (GSM 230) with a pole diameter of 38mm at the bottom, tapering to 30mm at the top, and a thickness of 1.4mm. They can be machine or hand washed, with flat drying recommended. Options include drip, line, or gentle tumble drying. To remove wrinkles, iron at high temperature when fully dry or at moderate temperature if slightly moist. Avoid ironing when soaked. 60" W x 72" H
