Product details
Add colour, glow and easy-clean practicality to your setup with the 8cm Glow Glass Stem 19/14mm Diamond Pattern, selected as a Billy Approved accessory for its quality, fit and smart open-bottom design.
This compact glass stem features a colourful diamond-style pattern, glow-in-the-dark detailing, side diffuser slits and a fully open bottom that helps prevent ash and residue from becoming trapped inside.
Available in Red, Blue, 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 come alive in darker conditions.
One of the best features of this stem is its fully open bottom design.
Instead of having a closed end where ash, residue and other muck can collect, the open bottom allows debris and cleaning solution to pass straight through.
Benefits include:
- Fully open bottom
- Less ash and residue getting trapped inside
- 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.
You get the benefit of diffusion while still having an open bottom that makes the stem much easier to clean.
