Question for sealed-collectors: Protective Cases?

[Pops_Ghostly]

I originally posted this on r/Megaconstrux, but didn't have much success. I am re-posting at an attempt for additional info from those of you who may have missed it, and possible have an answer. Thanks in advance :)

Hello all. I was wondering if any of you use any type of plastic cases, etc for storing/displaying your Mega Construx - if so - what do you use?

I know the size of packaging varies from set to set, but for example, what would you store the Halo Heroes size in?

I own a few cases that fit the Super 7 figures perfect, but are a bit large for MEGA.
