This is a set of 2 lint remover brushes. Both are unused. The following is a quote from the product description at the time of purchase: Color: Blue [Compact Design Lint Remover] This lint remover has a small and compact structure. It's easy to clean even in small areas! The popular cat towers are also getting rave reviews, with the lint being removed and looking sparkling clean! [3-layer structure to firmly remove lint] Instead of sucking it up like a vacuum cleaner, simply run the lint remover over the surface to firmly remove pet lint! You'll have fun because the lint comes off so easily! That's the kind of lint remover it is! [The lint remover's bumpy, coarse surface grabs the lint] Even on fluffy materials like blankets, the second bumpy, coarse surface firmly grabs the lint! [The lint remover's brush part is silicone design] The brush part of the lint remover is made of silicone, so you can use it as a lint remover again and again without damaging materials such as clothes and carpets. The lint attached to the lint remover brush can be washed with water, so it can be reused as a lint remover again and again! [Main places of use] ・Carpets, rugs ・Hallways and verandas ・Sweaters, knit hats, and other clothing in general ・Car seats ・Dining and kitchen mats ・Blankets, mufflers, etc. ・Cat towers, pet cages
