Pilling in wool, cashmere and yak products are perfectly normal and is caused by friction that creates surface tangles in the wool fibers. We want our products to last a lifetime, so we introduced this comb to help you take care of your knitted pieces. This comb is perfect for reviving your knitwear. To remove pilling, lay the garment flat, hold it taut and gently comb in one direction over the affected area. Don’t use the comb on delicate knitwear like merino wool or plain knitted garments.
