This waste basket has a self-stabilizing lid with a counterweight, which allows the lid to close perfectly after each use. Inside the container is a small ring to secure bags, making it so that the minimalist form of of the wastebasket is not disturbed. Birillo is a series of bathroom accessories designed by Italian designer Piero Lissoni for Alessi. The minimalist collection is made up of forms derived from the simple shape of a rounded square. By gently curving the base on these objects, Lissoni has created timeless designs which appear to float.
