This 23" percolator bong is a simple colour accented classic style by Genie Glass. Producing 9mm thickness tubing in this height is well worth it for the gorgeous look. A 12-arm percolator breaks up your hit into smaller bubbles, which cools and filters smoke - it makes for a great show too! Ice catchers in the tube let you drop in a few ice cubes in for an even cooler toke. The sleek design bong features a reinforced, bi-stable 18 mm joint, ideal for 14/18 mm down stem attachments. A roomy, thick, glass slide bowl with a 14 mm downstem is all included.
