These adorable little blocks are 40% smaller than their cousins in our Wedgit Junior Set; but otherwise they are exactly the same. You can even use the same design cards for both 15 piece sets. The new mini blocks offer a greater fine motor/manipulative challenge and can be fully integrated with all other Wedgit Sets. Comes stacked neatly in a black storage rack. Small size makes them perfect for therapy bags and as a "take along" activity.
