There will be a little problem when you iron your clothes with a common iron, that is, it's not very convenient to iron the place with buttons. Although it is only a small problem, designers still take it into consideration, so they make a slight improvement on the iron to solve this problem. This U-shaped button iron has a U-shaped notch in the front, so when you iron your clothes, it can go over the buttons and conveniently iron the areas around the buttons, eliminating the issue of unreachable places on the clothing.
