Magnetic Mix or Match Deluxe Vehicles Set

Seven vehicles, each in three magnetic pieces — and every piece fits every other piece. A car, a lunar rover, a submarine, a train, a hot rod, a tow truck and a plane.

Which means, inevitably, a submarine with plane wings and tow truck wheels. That's not a misuse; that's the design. The magnets pull apart and snap back with almost no grip strength needed, so a child who finds fiddly connections frustrating can rebuild a vehicle forty times without once getting cross.

21 pieces. The plane is about 23cm long.
