Human Kidney Keychain

This keychain depicts the human kidney, sectioned to show all of the details of the kidney's internal structure. Cleverly integrated into the loop which holds the keyring, is a magnified depiction of the Nephron, the functional sub-unit of the kidney. This product is accurately reproduced from nature and is painstakingly modeled and then cast in small batches in the USA out of genuine pewter.
