Comes in a zip lock bag, great for cigar box full of rolling papper
No mess and works as advertised.
I absolutely love these Boveda Humidipaks, they make short and long term storage absolutely “Pilot Proof” , ie, easy to use and foolproof!
Great product to help regulate moisture in your stash jar whether it's to gently rehydrate overly dry flower or to keep it fresh in storage for long periods. Just drop it in your jar and forget about it for a few months until it needs to be replaced.
