<p>Invisible zippers, possibly the most popular zip of our time. Available in 2 lengths, 25cm and 60cm. But these lengths are easy to adjust. Invisible zippers are namely easy to shorten, from a 25cm zipper you can easily make a zipper of any size smaller than 25. The same goes for the 60cm zips, prefer 30, 40 or 53 centimetres? No problem at all! At the back of your zipper there is a metal slide, move it to the desired size and squeeze it tight with pliers or something else. Just check whether the slider stays in place and, voilà, you can use the scissors to cut the zipper to size! Really very simple! So be sure to discover our many colours of 60cm lengths below!</p>
