Sound Proofing Foam, 3 Packs

Sound proofing foam. 3 packs of 12 (12×12) foam tiles. These tiles are vacuum packed. I open 1 pack, and it says it takes 48 hours to fully restore. It actually took about 7 days for them to fully restore on their own, so I would definitely use the recommended method of putting them in the dryer. They are about 1 tiles. After they fully expand, tiles are about 12×12×1Each pack comes with a roll of adhesive. impeccable for everyday use. supreme materials and excellent craftsmanship ensure long-lasting durability.
