Let’s just go with “Mix _” instead of “_ Case” with Matchbox. Hot Wheels resets every year with their case letter codes, Matchbox does not. So if I say “S Case”, unless you are really on top of it you have no idea what I am talking about. I am NOT on top of it, so I had to open the case before I filmed the video just so I could see what I was opening.
So this is Mix 1, the first 2021 mix from Matchbox. And there is some awesome stuff in it. The Plymouth wins for me, but there are a lot more model to like too. Enjoy:
