Joint tube for your joint/cigarette.
Ever rolled a joint before going out and kept it in your pocket for the return journey?
Can you feel the anger and frustration take over your senses when you reach for the joint a few hours later, only to find that it's now shrunk to about a centimetre long and your pocket is covered with tobacco?
As you defiantly cast the useless joint into the wet road... spare a thought for your good friends at grasscity.com, who sell protective joint holders for a a real bargain.
