【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. [Thickness 2mm] The sound insulation effect is affected by the areal density of the sound insulation sheet. By increasing the thickness to 2mm and reaching an areal density of 3.5 kg/㎡, the soundproofing effect is doubled compared to general soundproofing sheets. Outstanding sound insulation performance with a sound transmission loss of 23dB at a frequency of 1000Hz. There is also no radio interference (wireless LAN or mobile phone outages). [Easy to install] The soundproof sheet size has been improved to 30cm x 30cm, and each sheet weighs only 0.315kg. This is a convenient soundproofing product that can be easily installed even if you are not a professional. We can solve your problems such as, ``The area is large and it is difficult to install, it is difficult to cut properly, and there is no appropriate size, so it is a waste of leftovers''. [Safety Material] The soundproof panel is made of soft PVC material, which is eco-friendly and has excellent flame retardancy. Furthermore, due to its high density, it has excellent waterproof and moisture-proof properties, so you can use it with confidence. [Wide Range of Uses] When used in conjunction with compatible sound absorbing materials (sold separately by us), the synergistic effect can provide significant sound absorption and soundproofing performance. It can be used in a variety of situations, such as rooms, audio rooms, studios, home theaters, soundproof walls in apartments, and deadening in cars.
