Dabbers are the tools used to transport your concentrates to a heated surface on your dab rig. Dabbers are usually made out of glass or metal and will assist you in avoiding a mess while you consume your oils. Dab tools come in many different shapes, sizes, and styles.
Carb caps are domes that allow you to cover your nail in order to hold in the vapor giving you a much bigger dab! Some dabbers may also have carb caps on the end of them.
