Crotial Bell (also called Rumbler Bell) – Claw style.
Typically an Elephant / Animal bell from India.
Flat part fits like a button into a slot in the leather harness like a button does on a shirt, with the flat side towards the animal of course!
Many used around the animal in a necklace fashion, usually around the neck and belly and straps.
Also can be used as a desk bell (usually has an egg cup style holder with it then).
