I usually opt for clear "protection" skins like Best Skins Ever for my devices instead of cases. Usually it's not an issue, but I'm thinking of getting the Mario & Luigi 3DS XL and was wondering how the artwork is on the device? Is it part of the shell or is it painted on? Does it appear that it could be scratched off or such? The reason I ask is because I wonder if a skin like Best Skins Ever could remove part of the art upon removal. I'm trying to think back to all the devices I have ever applied this on, and I don't think it's been a problem in the past, but it got me thinking.
