NATIONAL GEOGRAPHIC Rock Tumbler Navulling - 1 lbs. Mix van echte agaat rotsen voor Rock Polishers Inclusief 5 sieraden bevestigingen en Rock Polijsten Grit, Werkt met alle Rock Tumblers

Arrived on time and in great condition

There was one or two decent pieces in this and overall not extremely bad but again with Nat Geo I always get a lot of small broken bits that will tumbled away to nothing. Pretty much what I was expecting from Nat Geo

These stones polished up nice and it was great seeing them all the stages of tumbling. Recommend for all ages.

Works great...a lot of time tumbling but so far it is what was expected.

These rocks are so cool after using the tumbler! Definitely worth it.
