For actually displaying medals or groups of medals, different preferences stressed protection of the pieces, but offered diverse solutions. Having the medals actually suspended from their broaches eventually will cause stress to the ribbon fabric and its fiber. Shadow boxes are popular, but in most cases prevent easy access to and viewing of the back of medals mounted in this way. So do not store the medals near corrosives of any type. This can refer to the wrapping medium, the wood in the box, a can of Drano next to the stowage box and so on.
Good judgement is required.
You can get these in a variety of sizes for very low cost. You can also add a hanger on the back and hang them on the wall. According to another supplier, display mounts are available in 11 sizes and three depths and offer great low-cost storage, display and security for medals. Shipping is expensive and damage is likely, since you are essentially shipping glass sheets. This is the biggest fault of museums who, in many cases, have vast inventories which never see the light of day.
