Highly recommend these beautiful plates. After purchasing the set, I have not taken my necklace off. After reading the research, I definitely see the value of having these plates to only protect myself but also my family. I now also use the Small Oyster Plate under my massage table for my clients. Not only are there so many benefits that come from these plates, there are also so many stunning designs and the service was amzing and fast and was also provided extra information when asked. Definitely better to be safe than sorry.
