This top quality material is invented and imported from Japan. Naturally, as synthetic fibers are used on our precious dolls, safety is an all-important issue. This modacrylic fiber, with its near authentic feel, has a high flame-retardancy and great resemblance to human and animal hair. Flame retardancy doesn't extend flame when it comes in contact with open fire. Kanekalong wigs do not deteriorate with washing, unlike other materials. Kanekalon Protex is the world's finest fiber for creating beautiful wigs, hairpieces, extensions and braids.
