Keep the box from the film pack, tear off the flaps and put it in your pocket. After you peel, fold the 'tab' half over onto the 'negative' half and drop it in the box. It works great for the 99% of the time you don't have a trash can handy. The developer goop is a little nasty and may cause a minor chemical burn if left on the skin too long. Just try and only hold it by the edges. The 'negatives' from 3000b can't be cleared or fixed - they have a white base. You can, however, let them dry WITHOUT TOUCHING ANYTHING (they'll stick) and then scan but the image quality is far less than scanning the print.
