This is a pilling brush from Ikemoto Brush Industry. The brush bristles are mixed with static-removing fibers. Brushing removes static electricity while removing pills and smoothing the fibers. 【Quality Display】 Handle Material: PS resin Bristle Material: Natural hair (pig hair) + copper ion-impregnated acrylic fiber String Material: Nylon fiber Cleaner Material: PS resin Although unused, I am selling it to declutter. I would appreciate it if those who understand that this is a home-stored item would consider purchasing it.
