Polly Plastics Polypropylene Plastic Poly Pellets - 2 lb Rock Tumbling Media for Enhanced Tumbling Action

Using this for the prepolish and final polish. Works very well. Because of the costs, I rinse and wash both off very well and reuse each, but only with the same level of grit.

These did exactly what I was hoping, I had tumbled stones for about a month and upon the completion I just wasn’t happy with the polish left on the last grit I used. I asked for some recommendations and after a few people suggested this product I decided to try them out and after 6-7 days the shine on my stones was great and it worked on both hard and soft stones. Definitely would recommend to anyone tumbling stones

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.

These pellets are exactly as described. They are packaged in a very heavy gauge plastic bag, so very little risk of ripping and ending up with pellets everywhere. I would give it 5 starts except that $17 seems a lot to pay for little plastic pellets in a gallon-size bag. I guess depending on how many batches I can reuse them for, that might make me feel better about the price.

I tried my first batch of rocks without using filler media and it didn't turn out like it should have. After further research I purchased the above plastic filler media and then some ceramic filler media and had great success. The ceramic filler media is for the 1st and 2nd steps while the plastic filler media is for the 3rd and 4th steps in the tumbling process. The plastic and ceramic do different things so make sure you get both in order to get the best results.

Just what we needed to add to our tumbler to get better results.

I'm new to rock tumbling and people I have spoken with have universally said their biggest complaint was the noise. The tumbler I bought was supposed to be quieter than average but I bought these to help out even more. Where I noticed a big difference was between the first and second grit I didn't add additional pellets to compensate for the loss of material in the first tumble and it was significantly noisier. In the 3rd grit phase I added new pellets to get the drum about 2/3 full and the difference in noise is amazing. Since I haven't run any without the pellets I can't speak to how it is affecting the performance of the tumbling vs without the pellets but I'm happy with the results I've seen so far.

Bought these to supplement the pellets that came with my new rock polishing machine. These are fabulous, much less expensive than any other brand and worked perfectly. There are a LOT, but with all the polishing I do and needing a fresh batch for each phase, this amount is perfect.

These work well and are long lasting.

Works as a great fuller
