The Halo Pretty Done Modular Beaker Bong is Prism Water Pipes' modular system on a beaker base. Like the rest of the Halo line, it comes apart into stackable glass sections joined without rubber, so you can rebuild it, run it at different heights, or replace a single piece instead of the whole bong. At $214.92 it sits near the top of the Prism range.
The beaker base is the difference here. A wider footprint holds more water and sits more stable on a table than a straight tube, which suits a piece you'll actually keep set up at home rather than move around. The modular joints let you stack additional sections for more filtration when you want it.
It's built from heavy borosilicate, and the glass-on-glass connections are the whole product — the tolerance between sections is what keeps it sealed and swappable. This is for the smoker who treats a bong as a system to configure and maintain, not a fixed object to replace when one part fails.
Across the Prism catalog the pattern holds: the Halo Mushroom Modular runs a mushroom perc, the Honeycomb Modular changes the diffusion, and the Percolated Beaker Double Stack takes the stack higher.
Prism prices the Pretty Done Modular Beaker at $214.92. If the tall modular look is what pulls you in, the double stack is the next step up in the same system.
