Like its predecessors, the new and improved The Beadsmith Ultra Thread Zap Battery Operated Thread Burner 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 bead weaving and stringing projects. Features that make it special are a retractable tip for added safety, a more ergonomic and compact design for greater comfort and the fact that it includes an extra tip, which stores in the battery compartment. The tool is battery-operated and works on two AAA batteries, not included.
