✔️ Product Contents: 6 soundproof felt sheets, 30cm x 30cm x 1.2mm each (each piece is a soft PVC resin piece + non-woven fabric on one side), 1 installation manual ⚠️ Mounting nails are not included! We appreciate your understanding and purchase (⋆ᴗ͈ˬᴗ͈)” ● Good soundproofing effect: According to the sound insulation test (see video), the sound transmission loss at 1000Hz is 19dB, which has very high sound insulation performance. By using it together with our polyester fiberboard (density 200kg/m3), the sound transmission loss can be further increased. ● Easy to install: The large soundproof felt of 30cmX180cm is cut into 6 lightweight soundproof felts of 30cmX30cm, and anyone in your home can easily install it. Each piece weighs only 190 grams, which is very lightweight. In addition, you can freely cut it using cutting tools such as scissors and cutters as needed to create a more beautiful design, and the figures will not be monotonous. ● Safety (harmless and flame-retardant) and quality assurance: This safety includes the safety of the material and the safety of use. The material uses soft PVC resin, does not contain formaldehyde, and can be safely installed on flat surfaces such as room walls, doors, ceilings, and floors. Flame-retardant non-woven fabric backing ensures safety during use. ――――――――― ♡ Immediate purchase 24h welcome ⭕️ No comment OK ◎ ♡ Limited to 1 item ✨ First come, first served ✨ Free shipping ✨ ♡ Welcome bulk purchases, please feel free to comment ♪ #yun's product list ＊ The item has been opened once for photography, but it is unused!!
