Tough to get out once you drop 'em in... If you don't want to use mason jars, mayonnaisse jars, salsa jars, pickle jars.......
the same thing i was thinking.. a snapple jar's opening isn't very wide, so trying to put in / take out your weed after all of your hard work is going to be a real challenge imo..
imchuck has a few great suggestions.. look in the fridge and see what kind of jars you have in there.. mayo, pickles, peanut butter and many more are perfect for curing so long as you're sure that you get all of the odor out of them before using them...
you can pick up a case of canning jars from walmar for under $10 or so, and i don't know anywhere in the us that doesn't have a wally world close by..
