These assorted 4” Four Knocker Hand Pipes offer a particularly carnivalesque take on the classic spoon pipe design. The bowl is offset by the asymmetrical placement of a glass knocker opposite the carb hole while an additional 3 glass knockers run the length of the conveniently sized 4” pipe. Colorful stripes decorate the glass bowl adding further character to these motley smoking pipes. Crafted from top grade borosilicate, these glass pipes are heat-resistant for extended use. Despite their eye-catching colors, their 4” size makes them the perfect inconspicuous size for use as a hand pipe.
