Really? I could only fit in like "two and a half" -- i.e. the third disc would protrude and I couldn't close the chest-door properly. Maybe I need to try again with a combination of different discs. I have noticed that Ravage is a bit thicker than the other Discformers... he's the only one that I can't put into the container and close it all the way. I probably used Ravage as one of the cassettes, so perhaps I need to try it without him.
