Magnetic Building Blocks 100-Piece Set

This set contains one hundred magnetic cubes designed for STEM and Montessori-aligned learning. Children aged three and up explore colours, shapes, counting, magnetism, gravity and 3D structural design through open-ended play. The cubes are made from non-toxic ABS plastic, with some food-grade MABS, and are free of BPA and phthalates. Rounded edges and ultrasonically welded seams keep the eight internal magnets securely sealed inside each cube.

Suits Growing Families and Mixed-Age Play

The larger 0.8-inch cubes and eight-magnet design give a firm hold that works for toddlers developing fine motor skills and older children building complex models. Buyers who need smaller pieces for intricate detail work or a lower piece count for a first trial should look at other options. The blocks are certified to CPSIA, ASTM and CPC standards and are sized to reduce swallowing risks. Compact dimensions make the set practical for travel, restaurants and outdoor trips.

100 Cubes with Eight Magnets Each

Every cube measures 0.8 inches and contains eight sealed magnets, double the count found in many standard sets. This magnet density determines whether structures stay stable at the scale a child wants to build. The standard sizing allows the cubes to connect with major brands such as Magna-Tiles and PicassoTiles for collection expansion. No fixed building rules are imposed, so the set supports castles, animals, movable scenes and collaborative group play.
