I bought the tungsten carbide one ring as well as Frodo’s necklace. I really enjoy both of these products and have worn both of them almost every day since they’ve arrived, with the ring being on the necklace a significant amount of the time. My skin is quite sensitive to metals and I wasn’t sure how it would react to these 2 products but I’m happy to say that I have had no reaction to any of the metals found in the ring or necklace. In the short amount of time that I’ve owned these products, about 2 weeks, they’ve shown no immediately noticeable signs of wear and although when I purchased the ring I wished I could opt out of the elvish engraving I now am happy that I have it since I the text subtle enough when you’re just wearing it but very clear and neatly written when you are looking at the elvish lettering.
