Jennifer K: This was the best value! Almost all other brands cost a lot more. These come in tubs with lids and a scoop. Well worth it!!

firemansflame28: I've started rock tumbling and enjoy the finds. Be they petrified wood, river stones or precious stones. Its neat and it keeps the grandkids occupied with their finds. It takes about a month to go thru the whole process. The foam worked wonders with our petrified wood. I know the instructions said 3 days, but we did 4 just in case and the results were awesome. Loved it. Would buy again.
The use is approximately 6 times usage. So good luck rock tumbling friends.

Maria del mar Pérez Prat: Más cantidad que con la compra del tambor de pulir, que solo llevaba unos sobres para un programa de pulir, aunque en la caja no he encontrado la cantidad que lleva y lo he buscado en la descripción del producto en Amazon, producto de calidad y bastante satisfecha con la compra de national geographic, tal vez el precio es un poco elevado

AndreaAndrea: Tras 28 días (7 días por step) y 3 días con GemFoam, conseguí que mis piedras brillasen y estuviesen lisas. La verdad es que no obtuve estos resultados a la primera, es un proceso lento, pero gracias a informarme y a prueba-fallo, conseguí que quedasen bien. Y el GemFoam posiblemente ha sido el causante del brillo.
