The ultra-fine tip allows precise application, with a filament tip designed for detailed work on threads and knots. Ideal for bead and rope weaving projects or other everyday tasks. The thread burner uses 1xAA (1.5V) battery, providing multiple hours of use. Align the battery with the pen body and insert it (battery not included). Insert the replacement tips into the thread pen, then press and hold the switch for 5 seconds to activate. After use, allow the tip to cool and replace the included cap. The thread burner replacement tip is compact when not in use, saving space. If the tips are loose, slightly bending them may improve fit. The tungsten wire tip may soften and deform when heated, so always replace the cap when not in use to prevent damage.
