41388-1 Friends 2019 85 parts 5.4% catalog rarity Beginner
Mia's Summer Heart Box (41388-1) brings portable beach adventures to life with its 85 pieces. This LEGO Friends set features a Mia mini-doll figure constructing a charming sandcastle, complete with an adorable baby turtle figure ready for play. The heart-shaped keepsake box, rendered in Mia's signature colors, opens to reveal a blue tiled base, cleverly resembling a miniature sea where Mia and the turtle can imagine a refreshing swim. Its lid serves a dual purpose, acting as a sturdy display stand for the figures during their creative building sessions. A decorated name tile, styled as a beach towel, adds a personalized touch to the scene. All elements pack neatly inside the heart box, securing the summer fun for imaginative on-the-go play.
