Rest assured that we do advertise everything we have for sale on our website, so if it's not listed there then we do not sell it. We also do not do any customizing of controllers.

You are welcome to customize your X-Arcade controllers to your liking without affecting the warranty (though we cannot support nor warrant non-Xgaming parts of course). 

X-Arcade Controller Artwork Overlay information. 

You can also chat with others who are experts on customizing at the BYOAC Forums.
