【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. Absorb Wave: The surface is profiled to create an uneven surface to increase the sound absorption area. Achieves effective sound absorption even in a small shape. Sound proofing wave (for speakers): Adopts a wave-shaped sponge that fits perfectly around the outer circumference of the speaker. Sound proofing wave (for inner panel): By attaching a 5mm thick soft sponge to the inner panel, it eliminates the gap with the door trim and absorbs unnecessary sound. Clip damper (for door trim clips): Reliably dampens sounds leaking from gaps in door trim clips and chatter. Strong adhesive sticks firmly and ensures long-term use.
