If it get an opaque aspect (after years) you can simply wax it or use a little bit of olive oil or linseed oil.
It is a good ring for people allergic to metals. In fact the brass inserts are not touching the skin of the person who wears it.
It is a unique piece, part of a limited edition made by different sizes. If it doesn’t fit you contact me because I could have some other available size (similar, not exactly the same, as they are unique pieces).
If you have any question or doubt about size write me!
