Silk top full lace w/thin skin perimeter wigs designed with its enhanced 4×4 inches to 5×5 inches of multi-directional hidden knots. Each hair is hand-tied and double knotted for security and longevity. The polyurethane perimeter strip is ventilated by hand using an intricate secure looping technique where the actual hairs are not knotted, but injected into the PU material provided the best realistic appearance of hair growing naturally out of the wig wearers skin.
