I needed a spiffy sticker dispenser for at work. Everything I found online was designed for you to pull the paper and the sticker comes out with out the paper. Field tests showed me that they want the paper with it and they will leave a huge trailing mess and skip stickers.

So this is version 2, it is designed to let them preview what's next and then they can tear the entire sticker off with the paper (yes it has teeth) Yay, less mess and the window serves as a way to advance the next sticker without it getting lost inside after they tore the paper off.
