The Fluctus by Naef isn’t your typical set of building blocks. The vibrantly colored pieces, which are made in Switzerland from European plantation-grown wood, can be pulled apart to create half-circle shells, doughnuts, and smaller cones. The remarkably versatile result: soaring towers, runway tunnels, silly faces, and just about anything a young imagination can muster.
