Grandson is enjoying working with his rock tumbler and his extended Rick collection! Polished rocks very nicely and gets good results. Takes time but does a nice job!

Very good value My grandson's really liked it we had a lot of fun and still are enjoying it. The age all depends on how engaged you are with the child you should supervise him with these anyway If a 2-year-old can really enjoy it then I think most children will as well.

I never tumbled rocks in my life so I purchased a tumbler. I just picked up rocks and pebbles from my land and started tumbling. Some came out cool and fun looking, some were just gravel. So I purchased this refill, all the stones/gems are super cool. Anything from Hematite to Jasper to Rose quartz. Kit contains 3-1 lbs bags of assorted stones/gems plus each of the four tumbling grits. It has an identification booklet and concise instructions. Pretty easy to follow...1 bag of rocks and 1 packet of grit...2 bags of rocks and 2 bags of grit and so on. The stones were all cool rough but can't wait for them to be polished. This kit will work on any tumbler no matter the brand.
