This set comes with a variety of magnetic shapes to build with, including 6 small squares, 6 equilateral triangles, 4 right triangles, 3 isosceles triangles, 2 small rectangles, 2 "C" shapes, 2 "T" shapes, 2 staircases, 1 door, and a set of reusable stickers. It has a popular house theme, featuring those staircases and unique "C" and "T" shapes, plus the bonus sticker sheet for added creativity. Certified as a STEAM toy by Dr. Gummer’s Good Play Guide in partnership with The Toy Association, it helps children ages 3 and up develop fine motor skills, bilateral coordination, cognitive skills, executive functioning, and creativity. It makes a thoughtful gift for young architects or designers in the making. If you're looking to expand the building possibilities, the MAGNA-TILES Metropolis or DX sets offer even more unique pieces, and all sets are fully compatible with one another. Built to last through countless hours of play, the pieces feature a signature lattice design to prevent cracking and secure rivets that keep the magnets safely in place. They're made from food-grade, non-toxic MABS plastic that’s free from BPAs, phthalates, and latex, with magnets that are easy for small hands to pull apart for frustration-free building. Designed for builders ages 3 to 99, MAGNA-TILES encourage meaningful, child-led play that is fun, engaging, and developmental, with no instructions or adult help needed.
