I created the Gundam Base exclusive G-Self.
The parts have been updated and the quality of the upper body has been improved. While the design was good, I felt there were issues with mobility, so this is a big improvement.
The ball joint at the base of the binder on the Perfect Pack is still prone to thread stripping, so it needs some adjustment.
The clear parts have been painted with fluorescent clear so that they react to black light.
I'd like to see them make a High Torque Pack based on this...
