Review on Explore Nature's Gems: NATIONAL GEOGRAPHIC Rock Tumbler Refill Kit with Mookaite, Kabamba, and More - Includes 8 Jasper Varieties, 4 Grit Grades, Jewelry Fastenings, and Learning Guide by Andrew Jones

We only completed the opening set and as each of the 4 levels lasts 7 days we couldn't release too early. Of course my grandson couldn't wait and wanted to check the progress almost every day and we think that every time we opened it we lost patience. Although the stones were smooth, they were not shiny. Now we will try to follow the instructions exactly to see what this batch will look like. The attached photos show that they polish beautifully and we hope for better results this time. I would like the refill kit to include a scoop to measure the required grit. In the original kit the required amount was in plastic bags, as this refill is in a canister there was no pre-measured amount.
