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 measures for home karaoke. It was quite effective, but I am 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 freely adjust the length and width with the clips, which is very convenient! If you attach a regular curtain in front, the soundproof sheet will be hidden by the curtain and will not interfere with the interior design. I threw away the original wall-mounting hardware 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 by convenience store/ATM should purchase only if they can pay within 30 minutes. #HalloweenOnMercari #HomeKaraoke #Karaoke #Noise
