Keeping your action figures in good condition is of huge importance when it comes to action figure collecting. Years and years of storage can wreak havoc on your collection should you not heed to certain pointers.
The storage of action figures can slowly degrade the value of your collection if you are not very careful. It is amazing what time and the continuous burden of certain forces in the environment can do to your collectible action figures.
Ensure that you never store your action figures in a soft sided container. If you do, ensure that the actual figures themselves are in protective casings to provide a little bit of protection. Any force that pushes against the actual action figures, regardless of the weight or actual pressure applied can do quite a bit of damage over a long period of time.
The pressing of any type of pressure against your collectibles will slowly, over time, cause the action figure to take on the impression of whatever is pushing against it. You may not notice at first, and if you are not constantly monitoring your stored action figures, they will absolutely become damaged without your knowledge.
Another very important issue when storing collectible toys and action figures is to ensure that the room is climate controlled. Action figures are commonly painted with a type of paint that may ruin and melt if the climate is not kept at a reasonable temperature. Heat for a short period may not do much damage, however, heat over an extended time can and will degrade the paint of the action figures.
When a climate is cold, especially at the level of freezing, the action figures can become brittle. Any shock or pressure on the figures can cause them to crack or even worse, snap in places. Of course, this is not healthy for the value of your collectibles.
One way to beat a room that is not climate controlled is to purchase a plastic container that can be sealed. This will keep the elements out and come close to maintaining the temperature of the internal storage of the container. You can even wrap the container in packing cellophane to assist with controlling the internal temperature. This is not the best method, but storing your collectibles in this manner can make them last for quite some time.
Last but not least, pay close attention to where you place the containers holding your collectible action figures. You do not want to put them near water pipes or heat sources, such as a hot water heater. Water damage would be a catastrophe if it managed to get on your action figures and stay for any amount of time. That would be the end of the value of your collection.
I cannot say that any collectible will last forever, but proper storage of your action figures will enable you to keep them for quite some time, and most importantly, retain their appreciating value.
