Well this iron called 'U-Button' is still in concept and I think it is a pretty interesting concept. When we iron our clothes traditional ways, sometimes the buttons from our shirt will block the way. With this iron, if you hit the special button, the tip retracts to reveal a U that slides under the button to give you a fully ironed shirt. This is the specialties of this iron. Awesome concept and I hope it soon turns to reality.
