What Makes this set WOW?

Double-sided scenery: The diorama wall panels are double-sided, which allows you to instantly change the background color from pink-purple to blue-yellow depending on your preferences.

Unique Minifigures: The set includes two figures, including a figure with a rare confetti print on the torso that previously only appeared on much larger collectible models.

Rich party accessories: The interior is filled with detailed micro-buildings, such as a cake with a candle, block balloons and gifts that can be freely placed on the stage.

Gift form: Thanks to the built-in "Happy Birthday" banner and compact design, the model perfectly replaces a traditional birthday card, serving as a durable desk decoration.
