This is a sleep brush I purchased new. I used it for about two months. I washed it in the washing machine about 3 times. Reason for selling: I bought a new bed and purchased a futon and pillow set, so I haven't been using it as much. It's prickly and feels good, and I would fall asleep quickly. Also, this product can be washed, so you can wash it immediately even if you sweat in the summer, keeping it clean. Thank you for your consideration.
