Rock Tumbler STEM Toy
$5
This STEM rock tumbler kit includes the tumbler, USB cable, and accessories. It also comes with coarse and fine grinding powders, polishing powder, and rocks. Great for young scientists exploring geology! As you can see from the pictures, all the parts are there. The box has some damage and the bag of stones came open, but nothing is missing.
