Burn-proof materials stretching down on both sides of the iron are parallel to both sides of its metallic base to prevent hands from getting burned. Its transparent shell shows clearly the part that is being ironed, and the V-shaped trajectory of its metallic base helps the surroundings of a button to be ironed more thoroughly and makes it easy to iron the rim of a button. The iron is powered with a charger which saves up space and is convenient to use.
