Fabric: Made of Italian "Sunshine" brand calfskin (1.0mm thick), it has been treated with liquid color dipping and moisture-proof, anti-fouling and other processes to make the leather surface softer and more comfortable, with long-lasting luster. Accessories: DuPont's PU molded foam high-density sponge is used. There is a protective surface on the surface, which can prevent oxidation and shattering. It will never deform after HD testing. Tripod: steel frame, disassembly and assembly.
