Glass vapour path
Clean-tasting borosilicate glass, nothing else.
A spare for travel
Two short stems in the pack, so a spare is ready when one is soaking.
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.

Review of Dimpled Stem (2-pack)
★★★★★Caleb HigginbothamVerified buyerLonger than OEM but still works great
It’s quite a bit longer than the original equipment but it works great. I’ve had it for a couple of weeks and it’s still good as new. It’s made from glass so it’s not indestructible but it’s held up fine with my highly active lifestyle.

Review of Slim Vibrant Beads
★★★★★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 Bubbler Stem
★★★★★glass_ladsolid upgrade
Didn't expect this much cooling from such a small bubbler. Easy to use, cleans fast, and feels well balanced on the device.

Review of Bubbler Stem
★★★★★Chris_MPerfect fit
Fits insanely tight on my LOBO, zero wobble at all. Feels really secure and the cooling is excellent. Glass quality feels solid.
Will a short stem feel warmer?
A little, as the vapour has less distance to cool. For cooler draws pick a longer or bead stem like the Ultra Cooling Beads.
Is it good for travel?
Yes, it's our smallest stem. See our POTV ONE travel setup.
How do I clean it?
Soak it in isopropyl alcohol, then rinse thoroughly with warm water. Let it dry fully before you use it again.
Does the Short Half-Black 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.
