>>7918530For displaying loose just google "hot wheels display case" there's a bunch of people who make acrylic "shelves" with compartments. Mattel makes one but it's kind of expensive for only storing 50 cars.
As for what to open and what to keep mint, that's on you. When there's a Car Culture release with really nice card art i'll usually double up and grab a sterling protector for the one I want to enjoy that way.
