Before you can dab, you're going to need a dabber tool. The dabber is used to pick up concentrates and put them on your heated nail. Dabbers can have different heads, including spoons, picks and spatulas. These different heads are for different forms of concentrate (shatter, wax, etc). The carb is a dome that you put over your nail to hold in vapor. Some dabbers have carb cap heads as well. Make sure to find the dabber and carb cap that best suits your dabbing needs.
