--------------------------------------------------- 【Voltage Compatibility】 Our products are selected to support international voltage ranges (e.g. 100–240V). However, please make sure your local voltage is compatible before use, as incorrect voltage may still cause 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 appropriate voltage or equipment. --------------------------------------------------- 【Large Capacity & Size】The length, width and height of the shielding box are about 12.5*10*6.5.

You can also put your mobile phone in the box while you sleep to avoid radiation damage. [Preventing radio wave blocking relay attacks] Relay attack principle: One person uses a special device to pick up and relay the radio waves from a key located away from the car, then a person waiting near the car uses the relayed radio waves to unlock the doors and make off with the car. [Places of use] It can be applied to many places. For example, at home and at work. When you get home, take off your shoes and put your smart key in this case at the entrance before entering. When you arrive at work, put your smart key in the case on your desk. This will eliminate the worry of car theft. Since it is a luxury item, it can also be used to decorate the place. [Relay attack principle] The relay thief approaches the driver and uses a radio wave amplifier to amplify the weak radio waves emitted from the smart key and send them to the thief who acts as the thief. The thief approaches the car while relaying the amplified radio waves, unlocks the car door without permission, gets in and starts the engine. [Luxurious and durable high-quality PU leather] The exterior is made of high-quality PU leather material, which is more durable than ordinary radio wave blocking boxes. In addition, the carbon pattern PU leather is full of luxury and feels good to the touch, and prevents water and dust from penetrating from the surface to the inside, protecting the fabric on the back. specification: Name: Signal Shielding Box Material: External PU leather, internal RFID fabric Color: yellow/gray Function: RFID information anti-scan/Anti radio frequency information leakage/Shield car key signal
