Product details
Add colour, glow and easy-clean practicality to your setup with the 11.5cm Glow Glass Stem 19/14mm Diamond Pattern, selected as a Billy Approved accessory for its quality, fit and smart open-bottom design.
This glass stem features a colourful diamond-style pattern, glow-in-the-dark detailing, side diffuser slits and a fully open bottom that helps stop ash and residue from getting trapped inside.
Available in Blue, Red, Pink, Green and Black.
The patterned section is designed to produce a bright green glow in the dark after exposure to light.
Simply expose the stem to a bright light to charge the glow, then watch the pattern light up in darker conditions.
One of the standout features of this stem is the fully open bottom design.
Instead of having a sealed end where ash, resin and other muck can become trapped, the open bottom allows debris and cleaning solution to pass straight through.
Benefits include:
- Fully open bottom
- Less ash and residue getting trapped
- Easier to rinse and clean
- Reduced buildup in hard-to-reach areas
- Faster everyday maintenance
- Great airflow
- Less chance of stubborn blockages
- No mucking around trying to clean a sealed stem end
The lower section features side diffuser slits that help spread airflow through the water and create more bubbles.
The combination of side diffusion and the open bottom gives you effective airflow while keeping the stem much easier to clean.
This stem uses a 19/14mm joint configuration:
- 19mm outer joint

Always check both the joint size and stem length before ordering to make sure it suits your bong.
