Are the plastic containers included in shipment or just baggies?

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.

Will this work good for making sea glass?

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.

Where should you dispose the grit

The grit is reusable ,use it over and over again.

Will this work to polish sea shells?

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.

Best rock tumbling grits on Amazon

I have been rock tumbling for over two years now and I have purchased this brand multiple times and will continue to be a return customer. The grits work exactly as expected for each stage of tumbling. Important notes:- Get the one that has the ceramic filler - not the plastics. The ceramic will last way longer and be better on your rocks.- Also - watch some YouTube videos on how to tumble rocks and switch between stages. There's some important tips to make sure you get the best results. Michigan Rocks YouTube channel has some great instructions on it.For the price and quality, couldn't be happier.

Best stage 4 grit for the $ on Amazon.

Shines up rocks with ease. If your a rock collecting nut that loves to polish rocks like me, this is some of the best prices and available stage 4 polishing compound on Amazon. Batch after batch, I’ve gotten consistent results from Poly Plastics grits.

Don’t go cheap on stage four!

Poly Plastics saves the Day! I had a pile of failed stage 4 batches collecting from poor quality polish. One week tumbling cycle with your polish turned them all brilliantly glossy. I’m relieved and happy to have found this product.
