Frozen Glycerin Bong Downstem | 18mm to 14mm | Multiple Colors & Sizes

The Ultimate Chill. Take your experience to the next level with our innovative glycerin downstem. Designed to deliver the coolest, smoothest hits possible, this downstem features a high-quality glass exterior filled with premium glycerin. It works just like a traditional downstem but with a powerful cooling secret.

How it Works: Simply place the downstem in your freezer for about an hour before your session. Because glycerin has a much lower freezing point than water, it becomes ice-cold without freezing solid or expanding. This eliminates the risk of the glass cracking. As smoke passes through the chilled glycerin chamber, the temperature drops instantly, resulting in an incredibly refreshing and smooth hit every time.

Long-Lasting Cooling. Unlike ice cubes that melt and mess with your water levels, the glycerin holds its chill for an extended period. For the best results, we recommend storing it in the freezer after each cleaning—that way, it’s always icy and ready to go whenever you are!

Universal Compatibility. This downstem features a standard 18mm to 14mm joint. It fits perfectly into any 18mm (or 19mm) female bong opening and accommodates all 14mm male bowls or bangers. This is the most common size on the market, making it an easy upgrade for the vast majority of glass bongs.

*To ensure a perfect fit, measure your current downstem from the bottom of the frosted joint to the very tip.
