Our silk base closures are lustrous, manageable and uphold the same quality as our lace closures and other products. Closures are not dyed as pictured. Highly favorable for the natural appearance. These 4 x 4 closures can last up to 2 years with the proper care and maintenance. They are all virgin hair cut from a single donor and vary from brazilian, peruvian or malaysian depending on the inventory at the time.
