I always knew the tube that you use to smoke as a "bat" and the container is the "dugout" both baseball terms. The tubes I have used were made from metal or ceramic. I prefer the ceramic bats and I always carry a spare due to clogging. Taste is okay, the convience is why I use one. Great for disc golfing. The dugouts that I have used in the past were made from wood, metal and the same material bowling balls are made of. Wooden dugout can get moldy, I prefer the bowling ball material dugout, super rugged, really easy to clean, and when I scrape the bottom for the last bit of meds, I don't end up smoking a bunch of sawdust instead.
