Dang, looks like one of all the pods from the 10 small Slizers \ Throwbots (although a few don't look matched up). Although just at a glance it looks like those might just be the discs that came with the sets. From a MOC standpoint, pretty much the more useless pieces from the Slizers, but hey that means nothing to collectors.

I kinda feel bad because I trashed a lot of my old canisters last summer to make space, but generally there doesn't seem to be much of a demand beyond the occasional crazy collector. Still, nice find, I'll be interested to see what you're able to do with these!

Yeah I'm sure some of them are messed up, haven't bothered to check and don't much care really.  When I say "possibilities" I mostly mean "hey these'd be neat to store special things in" so I don't have any plans to try and build anything with them yet.  Unlike RoboRider and BIONICLE canisters there don't seem to be any connection points at all, which is a shame.

As for discs they all seem like a generic variety, but the gold Millennium one looks neat.

Well, how many of the Toa canisters could attached to your belt?

What you have there is a utility belt.
