Sea Urchin The Sea Urchin is one of Ian's most well-known signature pieces, the detail in the carving is testament to his dedication and skill he puts into his work. The pipe has very thick walls combined with the tentacle design acts as a heatsink drawing heat away from the bowl ensuring an ultra-cool smoke. The slight curve on the brown Cumberland stem means this is a really well-balanced pipe that sits comfortably in the hand and will for sure be a focal point of any conversation whilst smoking.
