• Ice Catcher: Equipped with ice notches to hold ice cubes, cooling the smoke for a smoother inhale.
• Size: At 16 inches tall, it provides extensive smoke cooling and filtration, making it ideal for longer, smoother sessions.
• Diameter: The 50mm diameter allows for large smoke accumulation, ensuring bigger hits and better cooling.
• Base: Typically has a wide, sturdy base (either a beaker or round base) to prevent tipping and provide stability.
• Percolation: May include percolators or diffusers for additional smoke filtration, enhancing the smoothness of each hit.
• Mouthpiece: Comfortably designed for ease of use and a pleasant smoking experience.

This bong is perfect for those who want a larger, visually striking piece that evolves with use, offering an impressive combination of aesthetics and functionality for a cooler, smoother smoking experience.
