Precooler
Precoolers for glass bongs
Stylish and useful, these are the precoolers by Heisenberg. The practical glass inserts for bongs filter out a large part of dirt and ash particles out of the smoke before they get into the bong. At the same time they also cool your smoke. The result is that your lungs are less stressed and your sensitive oral cavity is less irritated. In short: more enjoyment with less risk of coughing. For every bong lover, the purchase of a good precooler is therefore an absolute must.
