Colibri Butane Fuel
The most recognized butane on the market and probally the best
if you need butane for anything wether it be for your portable vaporizer, butane lighters, or if you are just looking to make some good and tasty oil, this is the kind to get. you don't ever have to worry about your oil having any weird tastes or your lighter or vaporizer dying because of impurities in the butane.. Anyways, Now that i have tried Colibri i don't think i will ever switch back!
Don't try that other cheap crap, calibri is the stuff to use for the person who smokes oil. Best to oil extract and to use in you iolite, don't try to cheap out it isn't worth it
