These recyclable Fuzz Off Comb Refills can easily make your original Fuzz Off Comb and Fuzz Off Comb II work just like new! Sprucing up knits is a breeze with the Fuzz Off Combs. Heavy use can eventually dull the blade. Instead of replacing the entire Fuzz Off Comb, just switch out the comb and avoid unnecessary waste. We created this package of three refills for the comb, so you can continue to use the same handle. Refills are quick, easy, and safe to install. Old refills can be recycled (they're 100% steel).
