Share your thoughts with other customers
The MJR Tumblers Refill Grit Kit for 50 LB Rock Tumblers Silicon Carbide Aluminum Oxide Media Polish has received mixed customer reception. While some customers have purchased this kit multiple times and found that it works well for them, others have had issues with the final polishing stage not producing the desired shine. The kit comes with grit stages 1-4, but a customer reported that the stage 4 marked as 1200 was more likely 1000 and did not help their rocks shine. On the positive side, a customer mentioned that the product arrived earlier than expected and was exactly as described.
