The sharps disposal device invented by Han Pham is not only a great device, it has a powerful story behind it. We've been waiting to tell the story for a while! The Yellowone cap was one of the first ten devices featured on the Maternova Innovation Index and as part of that early set it was inspiring to us. At the time we discovered the device it was stuck at a stage that hinders so many entrepreneurial designers-- Han Pham had won a design challenge but could not find a manufacturer who would make fewer than 10,000 at a time. Her design was even featured in a 2005 MOMA exhibit.
