Kids will love the Tall-Stackers Pegs Building Set, which expands the learning experience and literally takes it to the next level. This first building set starts with a large, 11 1/2" Lauri crepe rubber base pegboard with 100 holes where kids will start their 3-dimensional adventure. They'll learn to think ahead and use their imagination as they plan where to put pegs to build the next platform. With 100 colorful pegs and 17 Lauri crepe rubber tower pegboards of various colors, shapes, and sizes, the building possibilities are endless. When not in use, all the 2 5/8" tall pegs and pegboards fit into a handy storage box with a carrying handle so kids can take their fun with them wherever they go.
