Here at OSO, we strive to have consistency in our products each and every time we make them. However, the art of anodizing isn’t a consistent process, therefore we can’t guarantee color consistency from one batch to the next. We are working with our partners to eliminate this obstacle, but feel it important to bring it to your attention. Thanks for your understanding.
