Please note that the Colored rim may have little black spot during the Anodizing procedure, which is unavoidable.
And The hub and rim of the set may have a slightly different color shade due to the different way of coating processes.
Please note that wheels can only be washed with "mild soap"
Do not wash rim with Natrium hydroxide based liquids(like "wheel wash" and "iron removers") , these will spoil the Anodization immediately, then the color will be faded.
