Temperature-adjustable curling iron. Probably 32mm. I bought it 2 or 3 years ago, but the tag seems to fade easily, so I haven't used it much, but the printing has faded. It heats up quickly, and seems to be a good iron, so when I go to replace it, they recommend I keep using it. - Model Name: Curling Iron - Color: Silver - Switch Location: Handle Thank you for looking.
