Long Bit Chip - V2 Era Double Sided
Released during the V2 Era.
Has space on the back for attachment of a secondary sticker for the A-70 Bit Finder accessory, as well as a side cutaway for positioning
This results in less plastic which lowers weight slightly, and technically makes it imbalanced.
Difference is negligible, but it is technically the lightest Bit Chip aside from not using one.
