National Geographic Rock Tumbler Agate Refill Kit - Educational Rock Polishing Hobby Kit with Gemstones & Grit, Jewellery Settings and Learning Guide Multicolor

Easy to use very noisy. Seem to be having to order lots of extra items for polish and buff.

Good quality, impressive gift

I buy these for my daughter that I only see once a week and she were disappointed

We got this as a top up for our 8yr daughter she has found it really easy to use with clear instructions planty of rough rocks including all the grit needed too

Given how expensive these are I thought the rocks would be better. The tumbler works a dream it’s just these were pretty uninspiring agates once tumbled

As always the quality is great ,the price and educational value exceptional.

I know your not going to get what you see on the box,but the rocks are not such amazing colours. Infact they are all white stones. The rocks are either massive or just grit that will ware away.Pretty disappointed.

Dont feel its value for money as many are so small if you tumbled them they would come out miniscule.
