It’s a hand held, cordless, hot filament cutting tool with interchangeable tips! It includes both the 38mm and 75mm V tips. This precise tool cuts and seals a perfect V on most polyester ribbon and fabric. It’s multifunctional! In addition to the V shape, you can turn the tip sideways to make straight cuts, angled cuts, patterns and shapes. It’s got a double safety ON switch and heat button to activate it. Also eliminates the dangers of a cord getting snagged on heated “constant on” tools; heats up in 3 seconds (requires x 4 AA batteries, not included)
