Repeated suggestions for correction seam to be ignored.
King and Cal King icons at https://www.earthing.com/all-products/fitted-sheet-kits.html are reversed and I also suggest offering sheets grounding cord for Europe without an adapter or attach the ground jack permanently to the adapter for European users. I have experienced an individual plugging the cord directly into the 220V live socket instead of ground (not understanding the need of an adapter) in Europe. Other than that I love all Earthing products and have a high respect for Clint - million stars wouldn't be enough... :)
