A stem (a.k.a. female piece) (no. 4 at the picture) is a component of bong, sits in the base and pokes out of the chamber at a degree higher than the water level. It holds the conepiece/bowl and enables smoke to pass through the water when in use. The stem collects resin over time which can clog the stem, and reduce the air flow through the water.

As we are makers of bongs, bubblers, pipes, one-hitters and other glass smokeshop goods, we can modify any of our bongs or pipes according to your needs. We make glass pipes and water bongs for a long time and our production methods are traditional and proved. It is a precise hand work and art glass blowing. See video from our glassworks!
Bongs offered in our bongs shop are light, but also hard and durable, made from Pyrex (PHX). The pipe shop offers glass pipes made from the same material. Our glass products are very popular also for their color changing effect (CCG), which is done by adding raw silver on the glass surface in high temperatures. Bongs, pipes and one-hitters with this effect are very cool and look crazy.
You can also get a free pipe or free one-hitter with your order, and you will get a set of free jax screend with every bong you buy here!
Photos of our products you see here are photographed so that most match the real appearance in normal daylight. Unlike many of our competitors, we are not trying to fool our customers.
