Easy Cleaning - Cleans Just Like A Traditional Piece

For everyday cleaning, add solution to the chamber and base, plug the openings (napkins work great), and shake.

For deeper cleans, let the solution sit for 10–15 minutes before rinsing.

Any store-bought glass cleaner works, or use a mix of coarse sea salt and 99% isopropyl alcohol.

Rinse with room-temperature water and let dry completely before freezing again.

We’ll also email full cleaning instructions after purchase.

What Is Glycerin?

Glycerin is a non-toxic, food-grade gel commonly used in food and personal care products.

When frozen, it cools smoke more efficiently than ice cubes and stays cold longer. Unlike water, glycerin doesn’t expand or contract when frozen — which means no added stress on the glass.

A one-hour freeze delivers a noticeably cooler experience that lasts through a full session.

How the Glycerin Cooling Works

As smoke passes through the frozen glycerin, the cold pulls the heat out before it reaches you. What lands is cooler, smoother, and easier on your throat, no ice required.

The Chamber and the Coil

Built to stay smooth, not clog

Think of it as two parts: the chamber holds the cold, the coil carries your smoke through it. The XL chamber is packed with 50% more glycerin than a standard one, so there's more frozen gel around every pull. The DNA coil is the path through it, two wide looping coils that keep smoke against the cold longer.

That wide-diameter design is also why it won't clog. Open pathways keep airflow strong and resin from building up, so the coil stays smooth and rinses clean, pull after pull.
