Famis Wrapp-It Styling Strips are designed to hold wrap hairstyles in place during the drying process. they are 40 in each boxed in different colours that are designed not to bleed or stain hair and sculp. I use these wrapps because they are efficiently stretchy and can be used for all thick and puffy natural hair types. Famis Wrapps are designed for all hair types for women and men as well. They are skin friendly and perfect for laying down edges. Liquid products do not leak through the wrapp can be used with heat from hair dryer and is not flammable.
