Microscope slide for bugs?

[Gobbleston]

Every once in a while we find a small bug here and there that we would like to check out with the microscope. We don't want to kill the bug because we want to see it while it's alive. But the issue is that I can't find any kind of containers of any kind to hold the bug. I've been using various things, napkins, whatever, with a light on top (usually a flash light, I just bought a little reading one for exactly this purpose.) But what I would like, is some kind of container for the bug so that it can be seen, but still mobile. In my mind, this container is like a small glass box, with a piece of glass on top that slides open or closed. I can't find any such item though. Any ideas?

You could use petri plate
