●Product Overview: The original Earthing Mat (EPP leather type) from Lilacrefe is a high quality mat that provides the leather feel of a sofa. This mat aims to allow for grounding through connection with the ground and balance electrical ●Note: To confirm whether grounding is possible, please check the grounding measurement kit instead of an electromagnetic wave measuring instrument. A simple electromagnetic wave measuring device that does not connect to the ground, so it cannot be measured correctly. In the unlikely event that a bad reaction occurs on the body, we also provide instructions on how to deal with the body. If you contact us directly, we can also inquire you to get an appropriate solution for you ●Grounding that connects to the ground can be used with a cord and connected to the ground. Please note that no cords are required (wireless) and cannot be grounded to the ground. If the cord is not in use, it can be discharged in the air. Discharge (discharge in the air) has properties that gather electricity in a place where electricity is prone to flow. Since electricity cannot be stored more than a certain amount of electricity, it is a mechanism that will discharge (discharge in the air) ●Main Features: Size: 39.4 x 19.7 inches (100 x 50 cm); Thickness: 0.1 inch (3 mm); Surface Material: Black/Conductive Leather; Back Material: Blue/Cushion Material; Mat Surface Resistance Rate: 10 - 3 - 10 - 4 Ω; Compatible Years: 3 - 5 years ●[Accessories] Grounding cord with built-in resistance 16.4 ft (5 m) / 3 grounding connection cord 3.9 inches (10 cm) / Threaded ground connection cord 19.7 inches (50 cm) / 0.4 inch (10 cm) button connection cord *If the cord is not long enough, please use the exclusive extension cord sold separately. In addition, if you use multiple grounding goods and only one grounding connection, please purchase a splitter (Earth Branch Part) sold separately ●Safe Design: The included original dedicated cord is made to Japanese Earth standards and is intended for use at home. Copper wire is cut resistant, durable and long lasting. Recommended grounding cord is the standard built-in resistor cord (built-in 100 kΩ resistor); Prevents electric shock, such as when it comes into contact with a leakage product. Reduces the noise (common mode noise) coming from the earth and is not suitable for those who have sudden grounding without resistors. *Please be aware that when using a cord without resistor. Use it above ●Material Information: EPP material (environmentally protection PVC, RoHS 2.0 compliant). *RoHS directive is the EU regulations that restrict the release of harmful substances in the human body and environment when disposing electrical and electronic products
