QuaDror building blocks are a cool system of play blocks made by architect and designer Dror Benshetrit, who made a discovery that L-shaped blocks placed together could “unfold” into a structural support. QuaDror blocks are the result. Each set comes with 10 blocks, which measure 3″ x 3″ and allow for some pretty fantastical creations to be created by kids and adults alike.
