This is a HITODOL brand styrofoam cutter. I bought this hot wire cutter, thinking I'd make a spot cooler out of styrofoam during the sweltering summer. ...Huh? ...Yes... I opened it, but the heat sapped all my motivation, and it ended up unused, gathering dust in the dresser. Now that I finally have some motivation, I don't need air conditioning, and my initial resolve has vanished... If anyone is thinking of making a spot cooler for next summer, perhaps for a child's summer vacation project, please feel free to use it. (If a child is using it, please make sure an adult provides support.) I threw away the box, but it's new. I would appreciate your understanding. Thank you for looking.
