Compact on the outside, but sporting an impressively broad little chamber, the "305" is a good choice for those who appreciate particularly flavorful blends. Each briar of the Tortuga series sports not only a tortoiseshell-patterned stem, but also a domed, shell-like cap with a foam-rubber stopper. The purpose of the latter is to preserve an unfinished smoke which one wishes to pick up again and finish later.
