Perfect Refill Set
Perfect refill pack. More than enough quality materials to keep us tumbling rocks for many, many months. Great value and includes instructions, which was very handy as we misplaced the ones that came with the tumbler itself.

Consigue el brillo de las piedras
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.

All the kit is very nice.
Very good grit, and the foam actually works for the fifth step. I was pleasantly surprised.
