SmartMax Start XL is a 42-piece magnetic discovery set built for young builders. Oversized, extra-strong magnetic bars (18 short, 12 long) and 12 metal balls click together into towers, vehicles and wild creations — with magnets strong enough to hold up to 60× their own weight. Ages 3+.
Every piece is sonically welded for durability and sized so little hands can grip and connect them safely, and a build guide helps spark ideas. SmartMax is a hands-on intro to magnetism and STEM, and all sets click together so the collection can keep growing.
