Glass Expansion Chamber for Incredibowl Pipe Mini m420 - 4-inch
The standard expansion chamber for the Incredibowl m420 is made of the same shatterproof polycarbonate used to make bullet-proof window panes, but this replacement expansion chamber is handmade using clear, borosilicate glass, in the same 4-inch size! It's a matter of preference, if you're a fan of smoking from boro glass, and you'll find that this glass expansion chamber is easier to clean and top-rack dishwasher safe. The Incredibowl Industries and m420 logo are applied on the tube in black, and two black rubber caps are included.
