This is a Chinese bow with an abalone lined from. These frogs are made in China and they have a nice look. The only problem is when you try to rehair the bow. Basically the inside of the frog is a plastic or resin material and the block hole is very tiny. The two sides are faced with abalone, but whatever type of glue they use does not hold. Sometimes once you take the ring off, both sides of the frog basically fall off. Then they need to be reglued back onto the center core of the frog.
