|Like its predecessors, the new and improved Ultra Thread Zap will trim, burn, or melt thread with one touch. It heats instantly with the push of a button! The extra-fine tip allows for precision application, making it ideal for finishing beadweaving & stringing projects. What makes the Ultra Thread Zap special are a retractable tip for added safety, a more ergonomic & compact design for greater comfort, and it includes an extra tip which stores in the battery compartment! Battery-operated (two AAA, not included).
