Anodizing/surface treatment disclaimer :

Anodizing is a serious chemical process that is fairly unstable. The shade of color can vary batch by batch. We do our best to make the color as correct as possible but we can NOT generate if the shade meets your imagination. Also to be noted that every monitor has its color differences. The color of the object and the color on your computer/ mobile device may be different.
