There was a problem filtering reviews right now. Please try again later.
They provide you samples to tumble with one packet of each level of grit. So a basic starter kit. I think that is great for any product. I didn't use their sample as I had my own to tumble. So excited to keep using this to tumble my treasures!

Pero hay que tener paciencia, tarda muchos días en pulir las piedras... algunas quedan del tamaño de una lenteja otras no. No desgastan por igual por su dureza y tamaño de origen.
Pero buen regalo.
