It comes with a trial set of grits, spare belts, and an excellent user manual that explains not only the usage, but it also gives good hints for rock selections. The rear page has an area where you can record the progress of your tumbles. The tumbler can be programmed for various speeds and days of tumbling. We quickly got it up and running with a selection of rocks from our beach. The 13 yr. old recipient was thrilled with it, even though there was a long wait for the final results. This is the case with all rock tumblers as there are multiple 7 day procedures with varying grits used. At the end, the rocks were smooth and well polished. We coated them with mineral oil for a nice shine. A warning: Because you're tumbling rocks, the unit is quite loud 24/7. It now has moved from the garage, where we could hear it throughout the house, to a back yard shed. It is definitely not recommended for an apartment dweller unless some sort of a sound proof cabinet is constructed. ## Features - ⚡ ⚡ ⚡ _xD835__xDC0E__xD835__xDC2B__xD835__xDC22__xD835__xDC20__xD835__xDC22__xD835__xDC1A__xD835__xDC27__xD835__xDC1A__xD835__xDC25_ _xD835__xDC0C__xD835__xDC1A__xD835__xDC27__xD835__xDC2E__xD835__xDC1F__xD835__xDC1A__xD835__xDC1C__xD835__xDC2D__xD835__xDC2E__xD835__xDC2B__xD835__xDC1E_ & _xD835__xDC01__xD835__xDC2B__xD835__xDC1A__xD835__xDC27__xD835__xDC1D_ _xD835__xDC0E__xD835__xDC2E__xD835__xDC2D__xD835__xDC25__xD835__xDC1E__xD835__xDC2D_: KomeStone brand owns the design of this rock tumbler - Belts are consumable, Please _xD835__xDC2B__xD835__xDC1E__xD835__xDC1A__xD835__xDC1C__xD835__xDC21_ _xD835__xDC28__xD835__xDC2E__xD835__xDC2D_ _xD835__xDC2D__xD835__xDC28_ _xD835__xDC2E__xD835__xDC2C_ _xD835__xDC1F__xD835__xDC28__xD835__xDC2B_ _xD835__xDFD3_ _xD835__xDC1E__xD835__xDC31__xD835__xDC2D__xD835__xDC2B__xD835__xDC1A__xD835__xDC2C_ _xD835__xDC1F__xD835__xDC28__xD835__xDC2B_ _xD835__xDC2C__xD835__xDC29__xD835__xDC1A__xD835__xDC2B__xD835__xDC1E_ _xD835__xDC2E__xD835__xDC2C__xD835__xDC1E_ - 90-Day Refund guarantee & _xD835__xDFD0_-_xD835__xDC18__xD835__xDC1E__xD835__xDC1A__xD835__xDC2B_ _xD835__xDC16__xD835__xDC1A__xD835__xDC2B__xD835__xDC2B__xD835__xDC1A__xD835__xDC27__xD835__xDC2D__xD835__xDC32_: _xD835__xDC08__xD835__xDC1F_ _xD835__xDC32__xD835__xDC28__xD835__xDC2E_'_xD835__xDC2F__xD835__xDC1E_ _xD835__xDC26__xD835__xDC22__xD835__xDC2C__xD835__xDC2C__xD835__xDC1E__xD835__xDC1D_ _xD835__xDC00__xD835__xDC26__xD835__xDC1A__xD835__xDC33__xD835__xDC28__xD835__xDC27_'_xD835__xDC2C_ _x - DIVE INTO THE FUN ROCK TUMBLING: KomeStone rock tumbler is for turning rough raw rocks into smooth gemstones, you will be very excited to see the rocks changes with each cycle.
