At Personal Fears, we design durable necklaces and chains made from 100% surgical grade stainless steel. We chose stainless steel because it's tough, long-lasting, and won't ever tarnish. Our necklaces are also hypoallergenic, meaning they won't cause skin irritation or turn your skin green. Plus, stainless steel is known to be scratch-resistant, making it perfect to wear everyday for life. The chromium in the alloy of steel forms a protective layer on the surface, which prevents rust and discoloration. Our necklaces are free of harmful elements that could harm your skin. Also, stainless steel is non-porous, meaning that it won't trap bacteria and cause irritation. Our necklaces are guaranteed for life.
