## Questions & Answers

**Q: Are the plastic containers included in shipment or just baggies?**
A: We switched from bags to jars several months ago.  There has been the rare instance of someone receiving bags due to some old product that was in Amazon warehouses but you should receive the product in jars.

**Q: Will this work good for making sea glass?**
A: Did you ever ask the  right person,yes it excellent for making sea glass.I Tumble with coarse for 12 hours then tumble again for 4 hours in soapy water to clean off the residue,Works great.

**Q: Where should you dispose the grit**
A: The grit is reusable ,use it over and over again.

**Q: Will this work to polish sea shells?**
A: This is a coarse grit so it is quite abrasive. If your shells are already smooth, I would use a Step 3 fine abrasive or Step 4 polish.
