It's funny to see people at different stages of the very same journey (!).
Zip-lock baggies that come with packs -> bigger baggies (rubber-band optional) -> small storage boxes -> larger storage boxes -> carrying cases that hold all your storage boxes.
Then when it comes to the mini's (and play-surfaces), the further steps of:
"off the shelf" display cabinets/tables -> custom-built furniture -> home renovations(!)
