Color Disclaimer: We want to let you know that monitor differences can also cause color variations. FDE anodized parts may have slight color variations. This is because anodizing is a complex process and there are factors that can affect color, such as the batch of parts produced and material composition. However, these slight differences do not affect the quality or performance of the product. In fact, they add to the uniqueness of each FDE anodized part. We appreciate your understanding and we are sure you will enjoy the custom product you receive.
