By far one of the best wigs Ive ever owned . The shipping was very fast . There was No smell, knotts are small . You dont have to bleach knots at all but you can . Hair was easy to curl , and also held the curls . Im on day 6 and my same curls are still in tact. If your looking for good quality units, this is definitely one of them . The hair is very soft . Hands can go straight through. Easy to style , very flexible. Unit can be a deep side part , or a long middle part !!! This is definitely the unit to buy. Dont hesitate!!!!! Get it.
