GRYND by PRTBL, a handheld grinder designed to give you the most consistent and efficient grinding for your herbs. Made from a solid block of aluminum the GRYND Grinder boasts a durable construction and teeth pattern that allows for consistent grinds no matter how many times you have used it. Notches on the sides give superior grip where its needed most to cut through those tough sticky herbs and stems. Cleaning your grinder just got a whole lot easier with a ceramic coating that prevents buildup and residue where most grinders struggle to spin after one or two times of regular use.
