Most of the small pipes that we sell are mouth blown. However many of the traditional set ups for these pipes are with bellows. We do offer any of these pipes to be set up as bellows blown pipes, however they are all special order. Bellows are a real important part of the small pipe. Getting the right amount of air in the bag helps the playing experience. If you play bellows blown pipes, and are in need of a new set of bellows, then these ones will serve you well.
