Anodized Aluminum are created in a process that uses dye, heat, electricity.  The coating in shiny and bright, and is the most cost effective way to add colour to your chainmail designs.  There can be colour differences between batches that are unavoidable, so we recommend buying more rings than you may need for one project, because the same colour in the next batch may not be the same.  The easiest way to damage the colour coating is scratching it with steel so we recommend using pliers with NO teeth, and you can even use Tool Magic to help protect them!
