What does "Mint In Box" mean to you? Do you have any suggestions for more nuanced abbreviations? Personally, I sometimes add "true" before MiB if the figure is flawless and twist ties and anything else that came with the figure is still in the box. I call it "MiB" if it has the insert (for G1), but is missing some paperwork or the figure has wear. I just call it "boxed" if it does not have the insert.
