The beads cool the vapour inside a stem only about 12mm across.
Two stems, so you can keep one clean while the other is in use.
Short and narrow, so it adds very little to a pocket setup.

Push the stem onto your DynaVap tip while the tip is cool, until it sits firmly.
Load the tip, heat the cap until it clicks, then draw.

When one stem needs a clean, switch to the second and soak the first.

Soak the stem in isopropyl alcohol, rinse with warm water and dry it fully.
A DynaVap tip and device are not included.

Review of Ultra Beads Stem for POTV
I really enjoyed this product. It has come in handy on several occasions.
Review of Long Glass Mouthpiece for VENTY
Loving my sessions with this glass mouthpiece! The beads inside make a real difference, the vapor is noticeably smoother and cooler. It looks great too. Next step: I’m definitely ordering the stainless steel bead version to test and compare!
Review of Ultra Beads Stem for POTV
Fantastic all that needs to be said
Review of Ultra Beads Stem for POTV
100% improvement. Way better than the stock stem.
Review of Cooling Beads Stem for Frolic
Cool stuff. I prefer direct connect with TM2 stem but it still a nice experience.
Review of Long Glass Mouthpiece for VENTY
This mouthpiece is brilliant, almost as good as a bubbler without the small hassle of adding water etc. Other than my glass bubbler it’s the first glass mouthpiece I’ve used. Going to order a 2nd one to rotate them so they’re kept clean
Review of Cooling Beads Stem for Frolic
Great addition to my Frolic. Bought twice, one arrived broken but following the returns advice on here I got a replacement in the post next day with no quibble, much appreciated. It slots directly into the cooling chamber mouthpiece with no obvious vapour leakage. Both cooling and flavour feel enhanced. Cleans easy with some iso in a sandwich bag. Very happy.
Review of Vibrant Bead Stem for TinyMight
Excellent product, delivers every time
Review of Vibrant Beads Stem for POTV
I love this stem, it cools the vapor. It’s great for one session, gets a little warm when you do two sessions in a row but way cooler than the POTV stem. Well worth the money.
Review of Vibrant Bead Stem for TinyMight
I like this straight stem, it’s purty! Maybe a version that’s shorter would be nice. What I want to know is exactly how many glass bb’s are in the tube?
Review of Vibrant Bead Stem for TinyMight
Long slow pulls feel much smoother now, especially with the TM2 on demand mode.
Review of Long Glass Mouthpiece for VENTY
slides right in with the gasket, no issues.
It is made for standard DynaVap tips: the M 7, M 7 XL and earlier M tips. Not the UniDyn, whose tip and stem are one piece. See the compatibility list.
Soak it in isopropyl alcohol, then rinse thoroughly with warm water and let it dry fully before use. See our guide to cleaning DynaVap glass.
No. The Slim Beads Stem is made by The Vapetrix to fit DynaVap tips. It isn't made or sold by DynaVap.
Same size and the same bead cooling, but this one comes as a pair and the Vibrant Beads Stem is a single stem with a coloured finish. See the comparison.
