My ready-to-ship units are made from the same luxury hair as my Queen Cambodian Collection. This virgin hair is silky soft, holds curls well and straightens beautifully! All units are made with a sewing machine and come with combs and/or an adjustable band so they can be worn glueless. Our wigs are more durable than handsewn units and can last years with proper care. If you like quality hair then you will love our Queen Collection Glueless units!
