• ★【Jars, Labels & a Scoop】Nice hard plastic jars with lids (as opposed to plastic bags). Bottle caps are very secure. Definitely they will not leak. Use the amount you need and set it back on the shelf for the next round. A scoop is included for the correct dose. No need to pour the material out, which possibly make a mess while doing so. They are neatly packaged and easy to read labels. Tip: you could put your tumbler on a foam pad to eliminate noise.
• ★【Professional Material】The final polish in this kit is aluminum oxide which is what the professional use (as opposed to silicon carbide), making sure that you can achieve a wet polished look. If you are expecting nice shiny stones you will have to run the last stage. The aluminum oxide is what really makes them shine (providing you have done everything else correctly).
• ★【Satisfaction Guarantee】 If you don’t get the satisfactory polished stones or there is anything else you are dissatisfied with, please contact us by E-mail, and within 24 hours, we will do our best to satisfy you or give you a full refund while you don’t need to return the product.
