Only have time for one hit? This is the perfect device for you. It is one of the smallest pieces available and can be as discreet and as mobile as you can imagine. The benefit is, of course, it gives you the ability to take a little something with you on the go – without being worried about lugging around too much equipment or product. In addition, because of their small size, these are fairly inexpensive and can be a great gift or travel tool.
