I found this going though some things but can't figure out what it's from. All the dice are wood, with the six on the outside having a standard 1-6 numbering, while the middle one counts by tens, from 10 to 60. The plastic case doesn't open and doesn't have any markings. They are loose enough you can 'role' the dice by rubbing the whole thing on the palm of your hand. It can kind of act like a fidget spinner, but I'm pretty sure it predates them. Any searching I've done has either turned up actual fidget spinner dice or sets of roleplaying dice, so I'm turning to all of you.
