Roots Glass 16″ Stemless Double Tree Perc Tube

Description

A 16″ thick glass bong built for daily driver use.

This stemless double tree perc tube is part of the Roots Glass lineup — built for daily use, fair price.

Standing at 16 inches tall, this heavy-duty tube is built from extra-thick borosilicate glass for durability you can feel in your hands. Its double tree perc system is where it really shines: a massive hourglass-shaped tree perc at the base provides unmatched diffusion, while a second stacked tree perc takes things even further, stacking bubbles for some of the smoothest, coolest hits you’ll ever experience. Both percs are welded directly to the bottom for strength and stability, making this a piece designed for long-term use, not just show.

The 18mm joint ensures rock-solid connections with your favorite accessories, while the stemless design keeps cleaning simple and eliminates the hassle of downstems. With its straight tube body, clean welds, and impressive function, this piece hits as beautifully as it looks.

Frequently Asked Questions

What’s the difference between a beaker and a straight tube?

Beakers have a flared base that holds more water and gives you slower, thicker hits. Straight tubes pull and clear faster with sharper hits. Comes down to preference — both work great.

Is a stemless bong better than a regular one?

Different, not better. Stemless bongs have less drag and look cleaner, but you can’t swap out the diffuser if you want different filtration. Regular downstem bongs are more modular.

How thick should the glass be?

5mm is the daily-driver standard. 7mm and 9mm are overbuilt — survives drops, feels solid in your hand, costs a bit more. Anything thinner cracks too easy.
