Sorry guys. There won't be brass plate option.
I'd like to make some explanations on why we charge for customization of colors and the lack of flexibility of options. In most CNC/anodizing factories in China, they deal with very large orders every day. When they are asked to manufacture only several brass plates, or to anodize one color for only several parts, they not only charge you more, but also treat you with poor manners. Sometime they don't even accept the order. Alsoran will be the one who deal with these problems. He honestly provided all the possible options the factory can provide. He should be rewarded for the extra work he will do.
The current rules/options for this GB were determined by considering the number of orders, price, options, costs of risks. There're always tradeoffs but this is our decision. I hope you can understand.
