**Q: Will the starter kit include all 9 kinds of stones or are there just some random rocks?**
A: This rock tumbler kit includs 9 kinds of stones as advertised,  weights around 1lb.

**Q: Can I tumble rocks we find at the park or do they have to be these special rocks?**
A: You can tumble any rocks you’d like, I suggest you get a rock identification app, plus a hardness chart. The rocks you tumble need to be the same hardness or the softer rocks will disappear… this is a lot of fun and the outcome is beautiful

**Q: Can this tumbler be used to polish metal washers?**
A: Based on two factors, yes it can.
#1 The washer must be a metal that could be polished in a conventional method, such as a buffing machine.
#2 That you are using a powder made for polishing.
I will add that I do not recommend polishing metal items in a tumbler,
