This are amazing and I've had them for a year. Wish there were more though! Really love the color schemes. They make me feel like the coolest cat ever, haha.
NOTE: to everyone saying they're a ripoff, PLEASE learn how to install stickers. Google it.
Also to the app developer, maybe include installation instructions in the description, a lot of people are technically illiterate and I see complaints like this ALL the time on sticker apps.
