The extra large GRAV® Straight-Based Water Pipe is 20" tall and made on 50mm clear tubing with black accents. Its geometric pressed pinch is both a splash guard and ice catcher. Its disco-ball perc forces water and smoke through tight restrictions, removing tar and debris. The straight-based water pipe comes ready to use with a 19mm GRAV® Cup Bowl and functions best with approximately 2" of water.
