Plenty of companies make these but you really can't beat the price and quality of the bristles really works on my hair.
I got my edge brush today and also got the TruEdge Controller and I'm loving them both! I got the pink one and its the best and sturdiest edge brush I ever bought. The brush is the perfect size and length so the bristles don't bend over when in use. If you don't have a edge controller and brush I HIGHLY RECOMMEND BOTH!!! Affordable price and great quality. Buying again and recommending to family and friends.
