From basic pegging to the challenges of sorting by shape and color, little ones love this time-tested favorite. Inviting, chunky shapes--bumpy on one side, smooth on the other-side over glossy pegs. This set promotes dexterity, sorting skills, and eye-hand coordination. Lauri pieces are washable and virtually indestructible, for years of safe, quiet play. Recommended for ages 2 to 5.
