【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.
[About clocks that synchronize time via radio waves]
The function of clocks that synchronize time via radio waves only works in the Japanese area. Please be careful.
✅ [70% thicker! ] In response to customer feedback that ``I wish it were thicker,'' we have prepared an extra-thick sponge with a thickness of 5 cm. It has even more sound absorption and cushioning properties than a 3cm sponge.
✅ [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, and you can use it immediately from the moment you receive it anywhere.
✅ [Efficient sound absorption with wavy structure] The wavy structure on the surface ensures a large sound absorption surface area. Effective against random incidence of sound. It effectively absorbs sound by attaching it to the inside of a car for deadening purposes, or to the walls of home theaters, piano rooms, music rooms, etc.
✅ [Wave-shaped structure efficiently absorbs shock] The unevenness of the wavy structure disperses shock and protects your valuables. 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: 5 cm Contents: 4 pieces Material: Urethane foam Features: Flame retardant Density: 26/m3 ✅ [Note] The package is packaged with corrugated layers overlapping each other, so it looks flat, but there are cuts and it separates into a corrugated shape. Upon arrival, please open and check the package.
