These rosin cloth sets of 2 (two) cloths are washable and environmentally friendly-the fabric is 100% cotton. Butterflies and stars print cloths are just the thing for wiping excess rosin off your violin & bow after playing. Convenient 8.5 x 5.75" size easily fits into your case. Fiddle accessories,in my opinion should be as distinctive as the players themselves. They make a statement about who's playing that fiddle!
