There is so much to this new design by master glass blower and inventor Chris Schuler. Did you know Chris Schuler designed the original Quartz Castle domeless nail? Pretty cool.
This four slit inline oil rig packs a punch! The thick base adds durability and stability. Each one is set off with a unique inside out frit design on the bottom. Chris adds an opal bead to each one, some in stock even have a crushed opal space bead!
Each one comes with the new deep dish Quartz Castle domeless nail and "hit kit" perfect fit Quartz Castle adapter.
Chris' new design adds a reclaim chamber to his inline oil rig. This helps catch the reclaim before it reaches the inline downstem or your water.
