This set includes 11 squares—4 mirrored and 7 glitter—plus 4 equilateral triangles. The mix of glitter and mirrored tiles adds a subtle sparkle to building time, while the reusable packaging doubles as a castle backdrop to inspire imaginative play. These tiles help support creativity, reasoning, problem-solving, and hands-on experimentation. It makes a thoughtful gift for children ages 3 and up, priced under $30. If you're interested in tiles that glow in the dark, consider the MAGNA-TILES Glow 16-Piece set. All pieces are designed to work with every other MAGNA-TILES collection. Built to last through years of play, 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 just the right strength for little hands to pull apart easily. MAGNA-TILES are enjoyed by builders from age 3 to 99 and encourage independent, open-ended play. We believe in Meaningful Play—fun, engaging, experience-based, child-led, and developmental.
