This set includes 16 glow-in-the-dark magnetic shapes: four small squares, four equilateral triangles, four right triangles, and four isosceles triangles, plus an LED keychain light to charge them. The pieces glow after exposure to direct sunlight or can be quickly energized using the included LED light. The reusable packaging doubles as a space-themed stencil set for creative activities at home. Designed to support STEAM learning, this set is often used for science-based play, experiments, and lesson plans. It makes a thoughtful gift for children ages 3 and up, priced under $30. For more shimmering options, you can also explore the MAGNA-TILES Stardust 15-Piece set. All pieces are fully compatible with other MAGNA-TILES collections. Built for durability, the tiles feature a signature lattice design to prevent cracking and secure rivets that keep magnets safely in place. They’re made from food-grade, non-toxic MABS plastic with no BPAs, phthalates, or latex, and the magnets are strong yet easy for small hands to pull apart. MAGNA-TILES are enjoyed by builders ages 3 to 99 and encourage child-led, meaningful play that is fun, engaging, and developmentally supportive.
