Collectibles are popular, or at least the act of collecting is commonplace. People have a tendency to collect things. Some of the items people collect are inexpensive, but too often collectible pieces are valuable. And, some of those collectibles are old and delicate.
It is necessary to protect collectibles. And, that protection has two different functions. One must protect valuable collectible pieces from theft, while protection from physical and environmental damage is a second concern. The optimal protection performs both functions while simultaneously allowing unimpeded view of the pieces in a collection.
Some common things collected are Hummel figurines, clocks, railroad memorabilia, steins, and sports pieces. Other collections might be of things from a single company, such as Disney or Coca-Cola. Or, perhaps pieces of sentimental value such as items that have been in the family for years.
