Vivienne 100% Virgin Weft Human Hair Bundle Invisible Genius Weft Extensions Jet Black #1
Vivien Human Hair Genius Weft Extensions
Genius weft is a new type of weft yarn, which is based on Hand-tied Wefts and is an upgraded version of Hand-tied Wefts. Genius weft hair extensions and hand tied weft are very similar, they are a good substitute for each other. It is the same as hand-tied weft, which is very thin, but Genius Weft has the advantage over hand-tied weft that it can be cut at will and has no back hair.
