This is a decorative cello bow with an abalone shell frog. Abalone shell frogs are very rare and not often seen. I am selling this to organize my collection. This is a good price for a decorative cello bow. The abalone shell frog is one of a kind in the world. I collect abalone bows because I love them. The abalone shell on the screw is detached, so it is being offered at a reduced price. If you win this along with the violin or cello bows I have listed, I will offer a discount.
