Specification: Material: 100% cotton fabric + silver fiber Color: Primary color 60 inches x 80 inches / 153 cm x 203 cm for double bed size HOW TO USE GROUNDING SHEETS: Step 1: Check your outlets for a ground connection. Connect it to the ground port on a grounded 3-prong outlet. Before connecting your grounding product, check if the outlet is grounded by plugging in an outlet checker. Step 2: Setting up the sheet 1. Place the grounding sheet over your mattress 2. Insert one end of the grounding cord into the ground port (third hole) of a properly grounded wall outlet or connect to the cable on a ground rod placed in the earth outside. 3. When you lie down on the connected sheet, all skin contact will transfer the earth's energy to your body as you connect the sheet. Step 3: How to wash and care for your grounding sheet Hand wash in cold, clean water. Note: Plug AU/ UK/US/EU (optional). It will be sent depending on your shipping location. If you have specific requests, please contact me when ordering. Durable and withstands hundreds of washes and low heat tumbles. Our kit includes a 98k ohm resistor that acts as a safety switch, but more importantly, it creates a more organized exchange of earth electrons and a better grounding effect. There is definitely a more powerful feeling with a 98k ohm resistor coupling. Extensive research has shown that a 98k ohm resistor matches the same ground potential of the human body for better results. Package Included: 1 x Grounding Half Sheet + 1 cable
