Great half wig
Color: Off Black 1B
I buy this wig like clock work. Its really cute and everyone swears its my hair. It does get tangled and starts to get puffy really quick but I do wear it like its my hair all day and take off when I'm home I also use it when working out so I do get it kind of sweaty but for the price this hair is worth it. I buy a new one almost every 2 weeks or so. This is a great inexpensive wig.

Outre synthetic quick fix
Color: Off Black 1B, Color: Off Black 1B
Sooooo cute, got so many compliments. Only knocked off a star bc i thought the curls were going to be a bit tighter. I added some moose and it actually loosened it up and looked even better, so yay! Easy to install, but my head is kinda small so regardless of me tightening it, it was still kinda loose.

Cute but wouldn’t order again
Color: Off Black 1B
First I’m going to say that the hair was USED before I received it and it was very obvious. But I had an important event to go to so I detoxed and cleaned the hair really well and let air dry. Cute hair and very curly and full. Wouldn’t buy again because why send something used? Especially a wiggggggg ?!?!!!
