Oval shape, more comfortable to wear, adjustable opening
The product material is solid brass, and the surface has been textured and worn.
Long-term unused, exposed to humid air, it is easy to oxidize and turn black, and it can keep bright when worn by clothes.
If you are exposed to excessive moisture for a long time, green patina is likely to appear locally. Please wipe off the patina with a coarse cloth and rinse with water.
