40cm Straight Tube Bong | Matrix & Spiral Perc Filtration for an Ultra-Smooth Draw with Crystal Green Accents

Standing 40cm tall, this water pipe is made from extra-thick borosilicate glass, making it heavy, strong, and built to last. This bong is built to deliver an incredible filter experience using two cooling levels. With a wide 19mm joint and a big comfortable mouthpiece pulling air is easy and hassle-free. Backed by a heavy, extra-thick base that won't tip over easily, it is perfect for solo daily use and fun parties !

1. Double Filtration for Ultra-Smooth Hits

Why settle for one filter when you can have two? Smoke gets cleaned twice—first by the lower green matrix perc, then by the upper spiral coil. This removes harsh heat so every hit feels cool and easy on your throat.

2. Scientific Design with Green Glass Accents

The clear vertical tube lets you watch the water bubbles stack up in real-time. The crystal green percolators inside add a great touch of color to your glass collection. Made with thick glass, it stands up to everyday use without worry.

3. Heavy Base & Easy 19mm Airflow

A good party bong needs to stay stable. We made this pipe with a wide, extra-thick base so it sits securely on any table. The wide 19mm joint lets air flow quickly, making it effortless to pull big clouds. Plus, the straight tube shape makes it very easy to clean with basic alcohol and warm water!

FAQ

Q: How do the two percolators work together?

A: The bottom matrix perc chops hot smoke into tons of small bubbles in the water. Then, the spiral perc sends the smoke through a longer path for extra cooling, making every hit super smooth.

Q: Why does this bong use a 19mm joint?

A: A 19mm joint is wider than standard joints, allowing more airflow. This makes it super easy to pull smoke through both percolator layers without feeling winded.

Q: Is this dual-perc straight tube easy to clean?

A: Yes! Because it is a straight vertical tube, you can simply pour in cleaning alcohol and coarse salt, give it a gentle shake, and it quickly washes clean.
