Swiss Holey Glass Downstem Low Profile 18mm to 14mm Reducing Slide Diffy Stem

Description

These Hand-Made Pyrex Borosilicate Holey Downstems feature spectacular diffusion!
Compared to the common 6-Cut, these feature 15 holes+, for over twice the percolation.
Please use my photos to illustrate how I measure; some measure differently.
These are low-profile, in that they fit into an 18.8mm Female ground joint and REDUCE to a 14mm Female joint. See images for illustration.
Depending on your region, 18.8mm is referred to as either, "18mm," or "19mm." They are the same.
Measure twice to order once.
