All I can say is that the cobs give a fresh and very tasty and intense smoke. I would not hesitate to have them around, and with a large army of these pipes, and rotate with the briar ones. And on top of that, their price is unbeatable. In short, the cob squeezes the juice of the tobacco, and a very real aroma is noted. It also avoids an unpleasant sensation of ash. This is my personal opinion.
