HALT PAPER DETERIORATION! HOW TO USE: Place an appropriate sized acid-free sheet of MicroChamber inside or behind your paper collectible or photo. The sheet does not have to cover the item 100% as acids will migrate towards the MicroChamber paper and be trapped. The MicroChamber paper will work indefinitely absorbing acid and neutralizing odors. NOTE: The price of some sizes of MicroChamber paper has increased what might seem a disproportional amount of money. Some prices did not change at all. The vendor of this paper changed the paper size they offer, and we were no longer able to cut some sizes economically. Although we are always reluctant to raise prices, we feel that thebenefits of this product outweigh the cost increase.
