I received this here. The previous explanation said it was made of human hair. It's great for concealing thinning hair at the back of the head, but it didn't work for me because my hair is light. I bought it thinking it would be easy to apply, about the size of a palm, without being too obvious. I'm selling both together at a discounted price. I only tried them on. The length is 18-19 on the left and 15-16 on the right. Please consider the dark brown one for the back of the head. I received it new from the previous seller, and it didn't come with a box.
