The ABS plastic used in the casing of some older SNES and Super Famicom consoles is particularly susceptible to oxidization on exposure to air, likely due to an incorrect mixture of the stabilizing or flame retarding additives. This, along with the particularly light color of the original plastic, causes affected consoles to quickly become yellow; if the sections of the casing came from different batches of plastic, a "two-tone" effect results. The color can sometimes be restored with UV light and a hydrogen peroxide solution. COUNT 5
