Use this comb to brush away pilling on garments made of natural materials.
Threads in fabric consist of many short fibers twisted together. These loosen and clump together into small balls. Therefore, it can be better to pull them out with such a comb than, for example, to use a machine that cuts them off. By pulling them off, you don't cut them and create new shorter fibers.
Pilling is completely natural, but with such a comb, you can easily give new life to garments or furniture that look a bit worn.
Adjust the pressure according to the material and experiment a bit :)
