Cases for Commodore C64 cartridges, available in several different colours.
These cases can be used for C64 cartridges with appropriate dimensions. Note that there are two quasi-standards, one is the slightly-smaller dimension that Commodore used, and the other is the "German standard" which has the mounting hole in a slightly different position and offers a bit more space. These cartridges are made in Germany, and they are therefore the "German standard". Please see our Wiki for the exact dimensions.
Please note that cartridges with additional switches, buttons, jumpers, LEDs, etc. (like MMC64, Retro Replay, MMC Replay, Nordic Replay) require you to make the approrpiate openings yourself.
