Generally, badges are made of metal materials and are prone to oxidation in the air. Therefore, a box with good sealing should be chosen, but it should also be easy to watch.

2. Find an airtight box, put some bamboo charcoal or other dehumidifiers under it, and then put a layer of plastic foam to separate it.

3. Coating wax on metal badges can isolate them from the air. Use plastic bags and sock packaging bags, cut them according to the size of the metal badge, and seal them with a sealing machine.

4. Find a piece of flannelette, wrap the plastic foam, with the corners facing down, and fix it with thumbtacks, so that the bottom plate is ready. The badge can also be pinned on a velvet cloth, which can be kept well and aesthetically pleasing.
