I believe this is what the youths call a "Big Mood".

This month's mail club goodies are all ready to be shipped out! This month's theme is wintery goodness, and includes a 5x7 postcard and 3 stickers! I'm pretty excited by how well these turned out <3 You can grab this month's set by joining the Cartographer tier on Patreon! They'll be gone forever after this month, so if you want 'em make sure you don't miss 'em~
