Magformers - Transforming Vehicle Set
This is not your typical building set! You can construct all kinds of 3-D figures with these super-powerful magnetic shapes. Magformer pieces (square, triangle and other geometric shapes) are included in each set and have encapsulated (tube-shaped) magnets within them that strongly pull the pieces together. The pieces always connect and never reject so you can easily build spheres, houses, towers, and more. Assembled creations are held together fairly securely so they don't easily fall apart, but when you wish to create something new, simply pull the pieces apart and begin afresh!
