Today's update introduces two new sticker collections - Xmas 2018 and Community Collection #4.
First one is the holiday Christmas-themed collection of 20 stickers. Each pack contains two stickers and can be obtained through in-game drops before 10th January.
Second one is set of ten community-created stickers from Workshop authors. Support them by picking up packs with those stickers from the store.
Have a merry Christmas and prosperous New Year!
Sincerely yours,
Santa.
