I’m a maker who sells handmade jewellery in a local handmade shop. I use stainless steel findings because they don’t tarnish or change colour. These ear wires are labeled as stainless steel in the description however after a short time on display in the store, the little balls and coils on the ear wires turned a bright yellow colour. The wire parts remained the original silver colour. I’m assuming then that the wire part is stainless steel but the decorative ball and coil are not. The product description should reflect that. I would not have purchased these if I had known that.
