This is the new and improved second version of my Black and White Birds of Brisbane design as a folding umbrella! 

These umbrellas fold down into a smaller, easier to carry form. They have a button to expand them to full size. This button may take a bit of force to press, and the resulting expansion is quite strong. You can press the button again while it is expanded to close the umbrella panels. You then have to manually pull the handle closed, which takes a bit of strength, as the mechanism is quite firm.
