✅ [No need to worry about it losing its shape] We carefully pack it to prevent it from losing its shape as much as possible. You don't have to worry about the sponge being deformed and unusable when you open it. ✅ [No worries about unpleasant odors] There is almost no unpleasant odor that is common with other products. There is no such thing as being so smelly that you can't use it indoors after drying it for a day, so you can use it right away from the moment you receive it anywhere. ✅ [Flat structure for a clean look and good sound absorption] The flat surface makes it look less noisy. Even after processing, it looks nice and clean. However, it does act as a sound absorbing material. It effectively absorbs sound by attaching it to the wall of a car interior, home theater, piano room, music room, etc. for deadening purposes. ✅ [Flat structure provides shock absorption that wraps around you] The flat structure evenly cushions your valuables and protects them. As a shock protector for effector cases, camera cases, attache cases, and computer storage. As a vibration prevention material for aquariums and motorcycle rear boxes. As a home-made filtration filter for aquariums, and as a material to prevent dust from entering ventilation holes. Because it is a simple product, it can be used for a variety of purposes. ✅ [About sound absorption and sound insulation] Sound absorption is the absorption of sound reflections. By absorbing sound, you can hear the sound clearly. This product is most effective if the material is soft and uneven, such as a sponge. Sound insulation is the act of blocking sound so that it does not travel, such as the sound of a piano or stereo, from coming out. Don't let outside sounds in. The materials must be hard and heavy, such as sound insulation sheets, plasterboard, and lead. *Sound insulation is not possible with this product. ✅ [Specifications] Size: 25 x 25 cm Thickness: 3 cm Contents: 4 sheets Material: Urethane foam Features: Flame retardant Density: 26/m3
