Rock tumbling enthusiasts, this Wirejewelry grit kit makes the whole process so much easier! You get everything you need for three complete batches - that's coarse grit, medium grit, pre-polish, and final polish all pre-measured and ready to go. The single-use tear packs are super convenient - no more messy measuring or guessing how much grit to use. Just tear open the appropriate packet for whatever step you're on and add it to your tumbler. The step-by-step instructions are easy to follow, making this perfect for beginners who are new to rock tumbling or experienced folks who want to simplify their process. The batch sizes are calculated for 3-pound capacity barrels, but if you have a smaller tumbler, you can just use half a packet per batch. From rough, dull stones to beautifully polished gems, this four-step process really works wonders. The coarse grit gets rid of major imperfections, the medium grit smooths things out, the pre-polish brings out the shine, and the final polish gives you that professional-looking finish. It's satisfying to watch your rocks transform through each stage. Having all the grits packaged together means you won't find yourself stuck halfway through a batch because you ran out of a particular grit. This kit takes the guesswork out of rock tumbling and delivers consistent, great results batch after batch.
