Becoming more and more popular each year, Vulcan Cylinder Shells set the standard in the industry and offer a great way to add a new level of variety to your shows. Quite simply, Cylinder Shells are the best method of delivering insert effects such as Tourbillions, Twisters and Whistles into the air when compared to Ball Shells. Vulcan Cylinder Shells employ a stacked double ring of inserts in most of the shells for maximum payload and visual impact per shell calibre. Carefully constructed using time honoured traditional methods, our shells are spiked and pasted to produce a device not prone to flower potting and which always produces large fully developed break patterns from one to three breaks.
