At Castle Glassworks, we designed this downstem to be the sweet spot between strong filtration and smooth airflow. The 9-hole design breaks smoke into smaller bubbles for better di ffusion, helping cool each pull before it reaches you. The result is a cleaner, more comfortable hit that works especially well for everyday smokers and anyone looking to upgrade from a basic open-end stem. Show more
