Acoustic Foam Panels 12 Pack 1" x 12"x 12" High Density Soundproofing Wedges for Wall Sound Proof Foam Panels Noise Absorbing Blocker and Sound-Damping Black Perfect for Studio Office Gaming Room

As long as you follow instructions it will puff up and be a good size, Everything is good except some of them had a slight warp on the edges ( unsure if it came like that or if it was cuz of my dryer settings ) but they are good

Very good product and i am very happy with it. I used them for soundproofing my music room.

After seeing mixed reviews I was definitely skeptical. It works for its purpose for sure. The adhesion is not great, but everything else worked out well. There was no smell, not that I could notice, and installation was very easy, I’d just suggest using another kind of adhesive maybe spray. It looks really good put up, and when it came to expansion, it was mostly expanded almost soon as I opened it. There were a few of them that needed to be teased but they worked out well

سيء جداً مو نفسو اللي طلبتو اللي كاتبينو 12في 12 واللي وصلني اصغر من كدا ولا يسوي شي

Piece came with manufacturing error, lacking the padding on the back. The other pieces are of good quality.
