Skiving Snackboxes are one of Fred and George's joke products. They are a range of sweets that make you ill, just enough to get you out of a school lesson when needed. The sweets are double-ended, colour-coded chewy sweets.
The Snackboxes include Fainting Fancies, Nosebleed Nougat and Puking Pastilles. The Pastilles are orange and purple sweets; the orange half of the Pastilles cause the consumer to throw up, and the purple half restores them to full fitness.
Fred and George have been developing the sweets all summer. They have been taking it in turns to test the sweets, which need a bit of work. They are having difficulty stopping themselves from puking long enough to swallow the purple end of the Puking Pastilles, and looked as though they had been duelling after they both tried Nosebleed Nougat.
