Spark creative building and early Stem skills with this 150-piece Glacier Castle magnetic cube set for kids ages 3 and up. Each cube features strong neodymium magnets to help structures connect securely for stable builds, from simple shapes to multi-layer castles and themed scenes. Dual-sided printed designs add more ways to play, letting kids create flat patterns or 3D builds while exploring spatial thinking, logic, and hand-eye coordination through hands-on construction. Made with reinforced plastic and smooth edges for comfortable handling, the blocks feature Uv-printed surfaces for bright, lasting color. Lightweight cubes and an included fabric storage bag make cleanup quick and travel convenient for playdates, classrooms, or trips.
