## Questions & Answers

**Q: The instructions say to use 4 tablespoons but the packet contains less than 1 tablespoon. Shoud I buy more or is i packet enough?**
A: My packets were short also, but in my 3lb tumbler it seemed to work with the amount provided. I also gave them 10 days of tumbling per step. only had an issue with the final polish because I failed to pick out the imperfect stones and possibly contaminated that step.

**Q: I have a code for a free refill pack (came with the national geographic tumbler i purchased last year). it expires 12/31/20. how do i enter the code?**
A: Its already expired

**Q: Why does my rocks not polish after 10 days?**
A: Is the tumbler broken or are you asking why you can’t set it for more than 10 days?   None of the 4 steps take more than 10 days generally speaking.  If you happen to be tumbling really hard stuff you can just add days as you go.  

However.  If you are saying the machine stopped working and is broken ~ Return it

**Q: How do you put the rocks in the earings?**
A: To attach a gemstone to the ring and earrings, have an adult help with gluing these accessories. We recommend a hot glue gun or an all-purpose adhesive sealant that can be purchased online or at your local hardware store.
