Jade is a body wave unit. 3-4  bundles of hair depending on the lengths with a 20 inch free part lace frontal.  This unit comes in 5 different lengths. The hair comes as natural color 1b. That can be worn as a half updo, side part or middle part. All wigs are made on a spandex Dome cap with virgin Brazilian hair. All hair is included unless if your choosing to build your own wig.
