Simple Crinkle is a very clever design; when flattened it is an iron that can be used on clothes and when bent, it is a hair straightener. I love it for its very practice approach and usability factor. When I am travelling I tend to pack in both, my hair iron and a clothes’ iron. So, if the tech guys can figure out a heating system that is both safe on hair and clothes, then this design is a complete winner! What do you think?
