SmartMax magnetic sets are ideal for young kids who love to build. Starting of with younger kids: The bars are big so they can easy snap two or three pieces together. Figure out which colours attract to other colours. For kids a little older, they can begin to build simple structures. As they get older, kids will build complex structures.
The 42 Piece set contains 12 long bars, 18 medium bars and 12 metal balls. Ages 1+
