Too freakin cool

"Switching from the metal perks to these is a game changer. You can see the entire flow of the smoke now and the glass is perfectly clear and nice and thick and sturdy."

— Deaven B. (5/5)

Science in Motion

"I really enjoy the clear glass stem - it makes explaining what is happening a little bit easier. And even easier to see with the Uplight accessory glowing for ambience."

— Renne H. (5/5)

Great

"Great"

Best perculator ever!

"I love these percs. So much better than the aluminum ones. My aluminum ones came scratched so I got these glass ones and it's bone appetit. Chefs kiss. muah"

— Ian M. (5/5)

Works great

"This is what is needed to create a more inert path for your vapor. If your material is water soluble then it is very easy to clean"

— Howie F. (5/5)

Single glass upstem

"Nice upstem. Bought one to try. It's ok but gets very dirty very quickly . Nice but I prefer the regular black ones to this."

— Barry G. (4/5)

Great design
