Polly Plastics propylene Pellets Rock Tumbling Media. 1 Lb. Rock Tumbler Filler Beads in Heavy Duty Resealable Bag.

I got a rock tumbler for Christmas. It was more for the kids, but we were looking for an opportunity to polish rocks we found at the beach and do it as a family. At the end of the 4+ week process, we found that the rocks were still a little dull. So we got these plastic fillers and ran it through the polish process again because we read that this helped with the overall shine . It definitely did. The rocks break down during the early phases of the tumbling process and they need some filler to keep the friction during the tumbling process to keep the barrel full. I think if the barrel isn't full, the barrel doesn't get enough friction to polish properly. It has been so much fun to do this with the kids. They love the end product. We already started the next batch of rocks. Fingers crossed, we are hoping for some more polished results. Overall, a fun family activity.

Product is packed well in a resealable heavy duty plastic bag. The parrot is cute as their logo. LOL. I was so glad to see these products are proud to be made in the USA and they are NOT made in China like most of the crap we buy. They sent an email thanking me for my purchase. How nice. Supplies came with my rock tumbler but not the plastic pellets. I know I can trust to order my supplies from Polly's when mine run out.

I ordered these pellets because I didn’t know about the ceramic stuff yet. These get the job done but if you’re like me and you dig a few rocks out of the barrel every few days to check on the progress you should go with the ceramic version because these tiny plastic beads will still all over your life! Same company sells a grit kit with a good size bag of the ceramic pellets, which I’ve got in two tumblers currently and like it much better.

I used these pellets for the final burnishing stage in my rock polisher. They did did a bit of shine to the stones. Will also use them to fill space in the tumbler when needed. They work well, easy to separate rocks from pellets in the end. They do get discolored but that is expected.

Keep the different stages separate after use. The grit will get slightly embedded in them during use. And you don't want a lower number grit in a higher number grit (coarser to finer) stage.
