Ami is a convention only kit. Rei, Minako and Makoto are the G-port ones. All kits are 1/8 scale and released in 1993.
Rei was airbrushed at the end of 2006. The rest were hand painted in 2012. My handpainting skills improved so much that you can't really tell the difference.
Rei was meant to be a standalone kit so she does not have the same base as the rest. I intent to replace her with School Uniform Rei later on.
You can see the individual WIP for each kit on my website
