Try Ebay, same place you got your tumbler.

Naturally, I looked there first, and have had an active search on it for a
looong time. But the only tumbling media I've been able to find on Ebay is
either very large industrial media (like ceramic chips 1/2" or larger) or
the fine abrasive media used for rotary rock tumbling. I've never seen
anything like small abrasive plastic pyramids on Ebay. But if you've seen
them, please let me know!
