hi we have lost the cord for this, is there one we can purchase?

They are great to deal with I would call them

With my rock tumbler kit i received 15% off my next purchase of refill pack. The savings will not apply to the 5# refill, why?

I have tried using this coupon with several different refill packs only for Amazon to not accept it. There seems to be a disconnect between NatGeo and Amazon regarding their promotional coupon codes.

How to identify tumbled rocks? i ruined the manual, its been years since college geology. any hints? seriously, all i can identify is tigers eye.

You can use the internet and now you can get a app from the app store for all rock's identification good luck : )

Are the stones ethically sourced?

As a science company we take great care in assuring that all our products are sourced ethically and appropriately.
