Have fun building incredible structures with SmartMax Start Plus! This 30-piece set includes 12 medium bars, 6 long bars, 4 curved bars, and 8 metal balls—plus a colorful guide with sample designs to spark creativity. SmartMax introduces young children to magnetism safely through oversized, durable pieces designed for little hands. The magnets are incredibly strong, able to carry up to 60 times their own weight, making extraordinary structures possible. Color-coded bars follow a simple rule: "cold" colors (blue, green, purple) attract "warm" colors (red, orange, yellow), while same-temperature colors repel each other—a hands-on introduction to magnetic principles. Built from high-quality materials with sonically welded bars, SmartMax sets are award-winning for safety and durability. All pieces are compatible with other SmartMax sets, so kids can expand their building possibilities endlessly. Perfect for ages 3+, this set combines tactile engineering fun with creative play.
