We guarantee that this product is made of 99.5% pure copper, with a solid copper interior in the tensor ring! However, in the first batch of products, we used a tin soldering process (resulting in a silver-white color at the joints). This led to a very small number of products developing cracks at the joints, which may have caused you to mistakenly believe that the product is copper-plated rather than solid copper. We sincerely apologize for this! In all current and subsequent batches, we will use copper soldering to prevent any cracking issues.

Due to the oxidation-resistant treatment, simply wipe the necklace with a damp paper towel. If oxidation occurs, soak it in a vinegar and saltwater solution (3:1) and gently brush the surface.
