Cant use it on any fabric or surface that is somewhat delicate. I got a hole in my cardigan and coat while using this so i would not use it on clothing unless they were really full of hair. Threads easily can get caught up. I only have one cat. This is perfect if you have a lot of shedding from several house pets. Not ideal for miniscule hair removal.
You couldn’t get any better for the price. It arrived rather warped but since it’s wooden that’s understandable. It grips fabric very hard so just softly brushing it against my sheets and clothing is more then enough to remove lint and lose string.
It immediately fell apart on the first attempted use. This came after I had ordered a similar item previously. That also was to be metal with a wooden handle. It arrived and was a very cheap plastic. I am not happy!
