I purchased a stash can from my local head shop last year for $15. It has been the single best investment I've ever made! It has a tight seal and discreetly hides up to half an ounce.
i shit you not my mom just came into my room like30 mins ago and said my room smelled danky, and i looked at her stoned as shit and just laughed..
i told her idk why and she buyer it, i got a little lucky.
