OG-1 - Cross Perc Bong by Trilogy Glass Works
The OG - 1 is the first and original percolator bong design by Trilogy Glass Works. If you’re looking for a cross perc bong that is reliable, classic, even kind of retro, choose none other than the OG - 1.
This 8", functional rig features a 14mm joint and a cross perc, consisting of 8 slits, for the optimum amount of percolation. The OG-1 sets the tone in style not only for the OG family but all of the glass rigs on the Trilogy line-up.
