Facebook stickers from Pixar artist rolling out now
Illustrator Matt Jones is the Pixar artist behind the new stickers, and from what we're seeing on early leaks, they look quite good. Stickers are a new addition to Facebook and are currently only available in the main Facebook app for iOS and the Messenger app for Android. As of this writing, the new pack hadn't rolled out to us, but when it does it will be listed in Facebook's Sticker store under the name "Finch".
Basically all of the Sticker packs available right now have a very Japanese-y/anime style to them, so it should be interesting to see a different style than those. Facebook has said that Sticker packs will be expanding to Messenger for iOS and the main Facebook app on Android soon.
