How to keep a piece.

Wear it. Take it off to swim or sleep if you like. A soft cloth is enough for silver. Gold asks for even less.

Avoid bleach, chlorine, and anything sold as jewellery cleaner with a secret. If the relief holds a little of the day, that’s all right.

The original paper is yours. Keep it out of the sun if you can. The metal will still be there when the paper isn’t.
