The Calibear 16" INV4 Tube is a tall scientific glass bong built around an inverted 4-arm percolator for increased smoke diffusion and water filtration. As smoke enters the main chamber, the INV4 perc distributes it between four arms before releasing it through multiple openings into the surrounding water. The straight tube design provides plenty of chamber volume while keeping the internal percolator completely visible.
Standing approximately 16 inches tall, this Calibear bong features clean clear glass construction with bright green accents around the mouthpiece, joint, base, and bowl. A wide reinforced base provides stability, while the removable glass bowl makes this piece ready for dry herb use.
