I still have my zocchihedron!

It does roll for a while, but stopping it faster is what the beads/sand is for. Without it (especially if it's metal like OP's photo), these things would roll like a golf ball. They still do, but I can get them to stop on a reasonably level table.

It also doesn't have empty spaces between the numbered faces; it's basically a sphere with 100 circular divots cut out of it. This means that it won't rest between values like the one in OP's photo is doing.
