This is the largest and most impressive bong from Manifest Glassworks. The Diffy Perc to Cirq to Cirq Perc Bong stands at an impressive height of 22 inches and is made from premium, 5mm thick glass. Smoke is diffused through three percolators - a Mini Diffy Cap Diffused Perc and two Diffused Mini CIRQ Percs, which provide unparalleled filtration and smoothness. The bong also features a Slitted Dome Splash Guard to prevent splashback and cool the smoke, as well as three ice pinches for an even smoother hit. The 14mm female joint is compatible with the included 14mm male high airflow pinched funnel slide. The bong is adorned with the iconic MGW Third Eye Lion logo and is made in New York, U.S.A.
