According to the information provided on the page of the Kitson site (where I stumbled upon this amazing new invention)..."Hemming My Way is the first snap hem with a revolutionary adhesive backing that allows you to snap under your long hem for flats and unsnap to slip back into heels." What will you find inside the package? Lets see...you will find, four adhesive plastic hemming devices. And did I mention they are removable and reusable for up to eight times!
