Obtuse 6" Stem

The Obtuse 6" Stem is a direct-fit replacement downstem built specifically for the MK-1010 Obtuse Beaker. At 6 inches, it delivers solid diffusion without overcrowding the chamber. Borosilicate glass construction holds up to regular use and cleans easily.

Highlights:
• 6" borosilicate glass downstem
• Built for direct fit with the MK-1010 Obtuse Beaker
• Standard diffused-slit design for smoother pulls
• Easy to clean with ISO and a brush
• Intended for legal use only

Downstems are one of the easiest parts to chip or lose, so keeping a spare on hand means your Obtuse Beaker is never out of commission for long.

*Per industry standard, length is measured from the bottom of the frosted joint to the tip of the downstem — not the overall end-to-end length of the piece. See our Downstem Measuring Guide for details.*
