While this isn't Chinese in origin, this speaks to those born in the year of the rat, or all our rat and mouse lovers.
A pert and lithe long-tailed rat rests atop a log. The watch key stem sports a bulbous shape that was textured to resemble bark or wood. The top and midsection are in silver over metal.
The remainder is in yellow gold over metal with a split ring for suspending on a chain or bracelet. A delightful charm for your neck mess or watch key collection.
