TORIBIO Sound Absorbing Material, Soundproof Sheet, Soundproof Door Curtain, Window Soundproofing, Sound Absorption Measures, Wall Noise Reduction, Indoor Acoustic Recording (Length 244 cm x Width 203 cm (1 panel)(Thickness 10mm) I was using this for soundproofing my home karaoke setup. It was quite effective, but I'm selling it because I no longer do karaoke. I purchased it new from the official store in April 2025 for ¥7,680 and used it by clipping it to the curtain rail as shown in the image. I will also include 6 clips, so you can attach it immediately if you have a curtain rail. * You can easily adjust the length and width with the clips, making it very convenient! If you attach regular curtains in front, the soundproof sheet will be hidden, and it won't interfere with the interior design. I discarded the original hardware for attaching it to the wall because I didn't want to damage the wall. I will ship it on the same day or the next day after confirming payment. Please refrain from purchasing if you have negative feedback. Customers paying via convenience store/ATM should purchase only if they can pay within 30 minutes. #HalloweenOnMercari #HomeKaraoke #Karaoke #Noise
