Tortuga Smooth (804 KS) (6mm)

The "804 KS" is essentially a beefed-up version of the "802" Canadian, just a touch longer overall, but noticeably taller, broad, and more capacious of bowl. 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.
