The best thing to do when you first receive wood gauges is to oil them with jojoba oil. Jojoba is a natural oil that will help to preserve and maintain the rich color of the wood. Oiling prevents cracking and can be frequently applied. If there is any detail carving, oil will enhance the image.
Wood is a fragile material, and even the larger sizes may break or crack if dropped. In addition, wood should not be exposed to water, at least for extensive periods of time. We don't recommend showering or swimming with your wood jewelry.
Our experience has been that wood is not as prone to warping as horn. It is lighter weight than both horn and bone and is comfortable to wear.
