How do I properly store board games long term?

Choose a storage location that is cool and dry. Pack the board games in clean, sound cardboard boxes and seal the boxes against dust, but do not put the game boxes in plastic bags (sudden changes of temperature can cause condensation to collect within the plastic). Several companies sell acid-free boxes and wrapping/packing paper for archival storage; using acid-free materials becomes more important the longer the games will be in storage.

Two important measures involve no cost:

1. Board games should be packed flat. Make sure

the board games are not leaning or unevenly supported.

2. Leave at least four inches of clear air space between the

boxes and any wall or floor (place the boxes up on pallets).

The air space will discourage minor incursions of both

insects and water. While this buffer space won't prevent

damage from major floods or insect attack, it is the minor

incidents that are by far the most likely to occur. If the

storage area has fire sprinklers, leave 18 inches clearance

between the boxes and the ceiling. Stack the boxes in

basketweave fashion, rather than one precisely on top the

other, to reduce the chance of the whole pile tumbling over.

If it's possible, have someone check the storage area periodically for signs of damp, water leaks, insects, or rodents.

i use those space bags where you get all the air out of them they are great for everything i live by them and it keeps everything dry and bugs out. good luck!
