The folks at ToyLab offer this description of their sort of hard to pronounce – GraviBlocks: “Enhance your child’s spatial awareness and cause-effect learning abilities with GraviBlocks. Gaining hand-eye coordination, concentration, and an analytical problem-solving approach has never been easier.” (Remember the spokesperson said, these blocks are for 18 months old and up to 5 or 6 year of age. For the youngest, it would be with the help of their parents of course) I did like that the clever storage box has a lid that can be used as a building plate. And I felt that the blocks are smooth and colorful. GraviBlocks: MSRP: $49.99
