The size, etc. are shown at the end of the photos. I have 12 pieces in hand, and I'm selling them in sets of 6. If you want all 12, please comment. Unopened. Color: Natural #AcousticPanel #IPANELLA #AcousticWallPanel #DIY #Soundproofing #SoundAbsorption #SoundproofingMeasures IPANELLA acoustic panels allow you to stylishly decorate your room's walls with easy, no-construction installation. The sound-absorbing material on the back absorbs unwanted household noises, such as conversations, pet noises, and the volume of TVs and audio equipment. The stylish wood grain can completely change the image of your room, and there are installation methods that allow you to restore the walls to their original condition, so even those living in rental properties can use them with ease.
