75/25 blend of Polyester/Polyamide. Package of two 16" by 16" towels. I love this towel because it makes polishing and waxing so easy. The tight weave quickly cuts through dry polish and wax residue for fast, smear-free, crystal clear results. Use with the Sonus Der Wunder Applicator (made using the same material) for easy-on-easy-off hand polishing and waxing. The Sonus Der Wunder Polishing Towel is superb on glass. Use it with Sonus Vision glass cleaner for streak-free, crystal clear glass. If you have stubborn water spots or stains, try using Autoglym Glass Polish with a Sonus Der Wunder Polishing Towel. The results are amazing. Sonus
