Micro-encapsulation is a process where fragrance is captured into a tiny bubble. The bubble is then applied to paper during the printing process. Each microscopic bubble attaches to the fibers of the paper. Only when you scratch the sticker is the bubble broken and the scent released. By encapsulating each scent, the life of Scratch-N-Sniff stickers is drastically increased. The Stink Factory uses the highest quality inks, scented oils, and printing presses.
