Cooling in a slim stem
Glass beads fill the stem, so vapour cools on the way through without making the stem longer or wider.

Pocket-sized
At about 75mm it stays compact for days out.
Bright and easy to spot
Coloured beads make it easy to find and nice to look at. Colours vary.
Take out the old stem
Pull your current glass stem straight up and out of the top of your LOBO or ONE. With the stem out, it's a good time to fit a fresh brass screen.
Push the new stem in
Push this stem straight down into the same opening on top until it sits snugly. No twisting needed.
Heat and draw
Set your temperature as usual and draw slowly.
Clean and swap
Soak in isopropyl alcohol, rinse with warm water and let it dry fully before refitting.

I 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.

Will it stay cool for back-to-back sessions?
It's noticeably cooler than the stock stem. Over two sessions in a row the glass does warm up, so for long sessions a longer stem like the Ultra Cooling Beads cools more.
Can I choose the colour?
No. The bead colours vary from stem to stem, so each one is a little different.
Vibrant, clear or steel beads?
They're all slim 75mm bead stems. Vibrant has coloured glass, the Slim Clear has clear glass, and the Slim Steel uses stainless steel balls and comes as a pair.
How do I clean a bead stem?
Soak the whole stem in isopropyl alcohol and give it a gentle shake so it reaches between the beads. Rinse well with warm water and let it dry fully. Don't push brushes into the beads. More in our bead stem cleaning guide.
Does the Slim Vibrant stem fit both the Lobo and the ONE?
Yes. It's made for the Planet of the Vapes Lobo and ONE and fits the same way on both. See the Made for tab.
Do I still need a screen?
Yes. Keep a screen in your Lobo or ONE so loose material can't get into the stem. Our 9.8mm brass screens are made for the Lobo.
