Wedgits 15 piece starter set is a great way to be introduced to the unique Wedgits building concept. The great thing about Wedgits is that there is no "wrong" way to build with this toy. This creates a sense of satisfaction with individuals and builds confidence. In addition to its uniqueness, Wedgits enhances fine motor skills, encourages creativity, and is great for tactile development. It encourages thinking and critical and problem solving skills as young children figure out how to build with this open-ended building toy. Recommended for ages 2-102!
