I purchased both items on Amazon. They didn't suit my cats, so I'm selling them. The green one is made similarly to a Furminator. It should remove hair effectively. I used it about once a week for about two months. I hardly used the white one at all. I will ship them in simple packaging, aiming to keep the height within 3cm. Shipping will only be on weekdays. I will use recycled materials for packaging. I will be careful, but cat hair may stick to the items due to static electricity.
