Plenty of glass surface
Large beads and a 120mm length give the vapour lots of glass to pass over before it reaches you.

A spare included
The pack has two stems, so one can be soaking while the other is in use.
A simple stem
No water to fill and no parts to line up. Press it on and draw.
Fit it to a cool tip
Push the stem onto your DynaVap tip while the tip is cool, until it sits firmly.
Heat as usual
Load the tip, heat the cap until it clicks, then draw.
Let it cool before removing
The long stem keeps your fingers away from the tip in use. Let the tip cool before you pull the stem off.
Clean the beads
Soak the stem in isopropyl alcohol so the alcohol reaches between the beads, then rinse and dry fully.

Review of Long Glass Mouthpiece for VENTY
★★★★★Green GidroVerified buyerCool stuff
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!

Cool stuff. I prefer direct connect with TM2 stem but it still a nice experience.

Review of Long Glass Mouthpiece for VENTY
★★★★★Peter ReidVerified buyerSO much smoother on your throat!
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
★★★★★AnonymousVerified buyerHappy purchaser
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 Beads Stem for POTV
★★★★★RipVerified buyerI love this stem
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
★★★★★Zachary FreemanVerified buyerI like this straight stem, it’s purty!
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?

★★★★★GeorgiaPerfect fit
slides right in with the gasket, no issues.
Will it fit my DynaVap tip?
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.
How do I clean it?
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.
Is this an official DynaVap part?
No. The Large Beads Stem is made by The Vapetrix to fit DynaVap tips. It isn't made or sold by DynaVap.
How does it compare with the slim bead stems?
This one is longer (about 120mm) with larger beads. The Slim Beads Stem and the Vibrant Beads Stem are about 75mm and much narrower. See the comparison.
Will the beads come out?
No. They are fixed inside the glass, so there is nothing to load, tip out or lose.
Is it a glass DynaVap stem?
Yes. The whole stem, beads included, is borosilicate glass. It replaces the standard DynaVap stem as your mouthpiece. Other glass options are the Spiral Stem and the Globe Stem.
