Manufactured for a perfect fit with the DMG PCB.Durable ABS ( acrylonitrile butadiene styrene) material from Japan.If you're looking for trimmed DMG shells, these are available here. With over 25 different color options, you can give your old console a vibrant, brand new look. While low-end aftermarket alternatives may deliver variable results, our shells have been carefully cast to reproduce the style and feeling of the original hardware. Our unique, in-house, Game Boy shells are cast using proprietary, high-precision tooling to ensure a final product that's as close to genuine shells as possible. The Neptune name has been chosen by the retro modding community during the Instagram 'Space vs Ocean' contest held on January 2021! This marbled DMG shell is a first of its kind, and due to how the plastic is cast to achieve this marbling effect, every Neptune shell has its own unique pattern.
