I collect stickers from various artists, big and small, from sheets to singles, and make my own occasionally; I needed a reusable sticker book since I was running out of spaces to stick art on, and had my eye set on MilkyTomato for a while. And I am very impressed :]
Though, with the amount of stickers I have, I should have bought a larger book in hindsight -- that's entirely on me. I still wholeheartedly enjoy my little booklet.
