I got a dozen "Missouri Pride" cobs in a pkg for ~$30 and they have the cheap plastic stems. I don't mind that at all.wow, how times have changed. When I last bought MM cobs, they were only offered with the black plastic stems, and forever stems had a black vulcanite and an amber acrylic. Now, MM cobs come with several different acrylic stems offered on certain styles and forever stems have a plethora of offerings... very cool!! Not all change is bad :
I gave a few away to some newbies and I've smoked only 1 of them so far. Still have 6 or 7 of them left. The one I'm smoking is holding up quite nicely.
They indent gently from tooth pressure and then "fit" a little more stable if clenching a bit. I have zero complaints about a cheap plastic stem on a $3.25 cob.
