Our stainless steel silver are pretty tough and won't tarnish or rust. It can get scratched, but your local jeweller should be able to polish them out for you.
You can polish your silver bangle easily with a silver polishing cloth. If it needs a clean, use a lint free cloth dipped in warm soapy (mild dishwashing liquid is fine) water to wipe the bangle clean. Then dry and polish with your polishing cloth.
Our Clasp style bangles are delicate and require a bit of extra care compared to our solid bangles.
Try to avoid hitting the bangle on any hard surfaces. We also suggest not sleeping with the bangle on as it may get hooked on the covers (or damaged while you sleep-thrash...)
