A. **Materials** 100% cotton fabric + silver fiber B. **Color** Natural color C. **Dimensions** - Option A: 90 * 230 cm, suitable for single beds - Option B: 153 cm x 203 cm, suitable for double beds D. **Features** - It is durable and can withstand hundreds of washes and dryings on a low - temperature setting. - The set includes a 98k ohm resistor, which acts as a safety fuse connection. It also enables a more orderly exchange of earth electrons, leading to better grounding effects. - Using a 98k ohm resistor connection may make people feel the effect is relatively powerful. - A large amount of research indicates that the 98k ohm resistor matches the grounding potential of the human body, achieving relatively good results. E. **Usage instructions for the grounding fitted sheet** - **Check the grounding condition of the socket**: Connect it to the grounding port of a grounded three - prong socket. Before plugging in the grounding product, it is advisable to check if the socket is grounded by inserting a socket tester. - **Lay the fitted sheet** - Lay the grounding fitted sheet on the mattress. - Insert one end of the grounding cord into the grounding port (the third hole) of a properly grounded wall socket, or connect it to the cord of a grounding rod placed on the outdoor ground. - Once the fitted sheet is connected, when you lie on it, any exposed skin contact may transfer the earth's energy to your body. - **How to clean and maintain the grounding fitted sheet**: Hand - wash it in cold water with pure water. F. **Precautions** The product comes with different plugs (US, Australian, EU, UK plugs) and will be shipped according to your shipping address.
