This is a set we made up for those who wish to pack guns, ammo, or any other valuables away for long term storage. It comes has an 81mm ammo can that measures 23"x13"x5.5" and enough dessicant that is rated for more than double the airspace in the can for extra protection. The dessicant will need to eb reactivated by placing it in the oven (directions are on the package, a small toaster oven works great), then pack your goods in, add the dessicant, and seal it. The dessicant will absorb all the moisture in the air so that your valuables will not rust or have corrosion and the can will not sweat or condense inside is stored in a cool place.
These are a great way to protect your goods in a humid enviornment or if you are storing them away long term!
