The 9 Best Rock Tumbler Grits
This wiki has been updated 21 times since it was first published in October of 2018. It's not often that a hobby is educational, fun for all ages, and not terribly expensive to get into, but collecting and polishing stones definitely ticks all these boxes. After you invest in your machine, you'll need rock tumbler grits, which are the media that help grind, shape, and shine those items to perfection. We've got a variety for you here, including all-inclusive kits. When users buy our independently chosen editorial choices, we may earn commissions to help fund the Wiki.
