“I got the EillishPops advent calendar for my little sister because she is a BILLIE STAN and DUDE 😂 she teared up opening the first door. She said it feels personal to real Billie fans, which made it hit even harder. 10/10 gift.”

“Actually obsessed rn 🤣💚”

Didn’t think I’d like it this much but this calendar is lowkey the highlight of my whole month 😭💚 The surprises are way better than I expected and it feels super personal if you’re a Billie fan. Literally couldn’t stop opening doors lol.
