Marvel/X-men United Villain storage box

This is a small set of inserts for the board game Marvel United to properly store some big minis from the villains. 

I wanted a way to better store minis from big villains like Onslaught or Brood Mother which most inserts that I found never really worked out, so I made these, it worked fine for me and I always separate the villains I most use this way. 

Can fit heroes too, though Anti-heroes may be hard to fit all sleeved cards, you may want to resize a bit for this.
