【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. Three types of soundproofing materials are included to eliminate the gap between the inner panel and door trim. Includes sound-absorbing material to suppress unwanted sound reflections from the speakers. Adopts virgin butyl rubber with a high specific gravity of 1.8, which is easy to use. It has high adhesion and ability to follow uneven surfaces, and does not require specialized tools during installation. Adopts a 2-way specialized spatula that can be used for removing door trim and installing butyl sheets.
