A pipe that has a “plug,” a disc that sits on top of the tobacco. You put it on the tobacco after you fill your pipe. It’s light in weight and lets air go in. Each time you need to light the tobacco, you press a small – almost invisible – button on the side of the pipe, and the heating coil inside it warms up quickly as you pull on the pipe as you would while smoking. When the tobacco is lit, you just press the button again to stop the heating.
