The 25 hole crepe rubber pegboard works well with these tall stacker pegs. The large plastic pegs (1" diameter by 2-5/8" long) are easy to grasp and place and each set contains 5 of each color (red, green, yellow, blue, and orange). These pegs also work well in the Big-Little Pegboard and the Large Lacing Tiles. They are also included in our Peg-N-Lace Set.
