KQJQS 12 Pack Soundproofing Foam Panels - 30x30x2.5cm Acoustic Wall Tiles

I would give zero stars if I could. In the description, it says that this is a 12-pack set of sound-proofing tiles, but when I received the package…well, the first thing that I noticed before even opening the package, is that it felt super light, as if nothing was inside the plastic packaging. Come to find out, as seen in the picture, there is only one piece of very thin, cheap foam material, with no other materials to give it support. I mean, how can you sell a product like that, really? The description is false. Am returning without a doubt. Walmart should take this seller off of their list. Bad name!
