Not too big, not too small - just right for smokers who want room to breathe without sacrificing flavor. Castle Glassworks’ 16-inch bongs hit that Goldilocks zone where smoke gets properly cooled but terpenes don't get lost in the process. 

Why 16 inches works better: 

• Optimized airflow - Enough height for cooling, not so much that you lose flavor 
• Stable but manageable - Fits on tabletops without dominating the room 
• Thick glass walls - 5mm+ glass with reinforced joints 
• Ice-ready - Most feature pinches for cooler hits when you want them
