This is a battery-powered cutter that easily cuts styrofoam. It allows for easy curved cutting, which is impossible with a utility knife. I used it only once and no longer need it, so I'm selling it. The included heating wire is also unused, so I'll include it as is. Operation confirmed. Please prepare two size D batteries. Since it was only used once, it's listed as "like new." Please understand that it has been stored at home. Please refrain from purchasing if you are concerned about minor details.
