The PRUF storage jar from White Rhino is a two-in-one storage solution that allows you to conveniently store your dry herb and concentrates in one travel-friendly container. The PRUF is a glass jar wrapped in a silicone body for protection against accidental breakage. The PRU storage jar features a large compartment for herb storage with a viewing window so you can always see how much you have left. The bottom cap comes off to reveal an all-silcone, non-stick, large concentrate storage compartment. Quit carrying around multiple storage jars and containers and switch to PRUF.
