Superasco is an invention by Giuseppe Parodi, the founder of Parodi & Parodi. It is a double-action sink plunger. Not a classic one. Its strong string and its movable handle guarantee the maximum adherence to the sink with the minimum effort.
How to use it: you should apply the plunger to the sink, closing the side holes of the sink (if any) with a hand. You can easily remove the plunger rotating the handle. Doing this, you’ll get the maximum power from Super Asco.
