Viotech Cello Bow Cushion Grip is a comfortable, ultra light hypo-allergenic neoprene foam grip that makes for a non-slip, easier bow hold ; 2 per tube
These are wonderful! I hurt the corner/tip of my thumb, and these cushions saved my cello career! I pull it up over the edge of the frog, to cushion my thumb. I promise, you will love these!!! When they get "smashed" down from use, I turn them to the other side, and have also taken them off and put them on the other direction. The best $9.95 you will ever spend!!!!
