Cutting Styrofoam made easy! With the Styrofoam cutter, you can easily and cleanly cut Styrofoam into your desired shape or size. The cutting wire of the hot wire cutter is heated by batteries. By pulling apart or squeezing the ends of the bow before tightening the wire, you can adjust the temperature of the wire and set it for working with different materials. This way, you can use the Styrofoam cutter not only for Styrofoam or Styrodur but also for materials like foam and sponge rubber. For clean cuts with the handheld device, always ensure that the cutting wire is taut. Additional product details: hot wire cutter, battery-operated, 1 roll of cutting wire, instructions.
