J-Hooks or Sherlock Pipes are glass pipes with a 18.8mm female joint allowing easy connection to a wide variety of male glassware and vaporizer adapters. J-hooks are used without water and serve to significantly cool the vapour on the way to your mouth while preserving all the flavour. They add significant cooling and extra length to your vapour path and if used upside down you can keep your vape at eye level so that with the right setup you can watch what's going on inside! They are made from high quality seamless borosilicate glass with a flat mouthpiece for improved comfort.
A great advantage of this style of J-Hook is, due to the mouthpiece design, they can be filled with 4mm (or larger) glass balls to provide additional cooling! Residue will collect on these in no time, keeping them in place when they've cooled, allowing for this setup to be carried around as part of a portable setup!
When not filled with balls, these J-Hooks can be placed upside down directly on top of any 14mm or 18mm male adapter to add extra length and cooling to your vapour pathway.
