What does "Carb Cap" mean?
Definition: Used in dabbing, where you put concentrated weed onto a nail (hot surface), and then smoke the vapors. The carb cap fits over said nail and allows you to vaporize a full hit at a lower temperature. This lets your weed keep its flavor, which becomes forfeit at higher and higher temperatures.
