We tested many toddler wood block sets before choosing these! Surprisingly, some toddler block sets are made of rough, porous wood, with colors that actually bleed. Our choice: smooth, high-quality wooden blocks that feel great to hold, are crafted to last, and are sized for smaller hands. Outstanding value! Includes 100 blocks and storage tub with shape-sorter lid, which makes clean-up part of the fun. Great for eye-hand coordination, creativity, and color and shape recognition. Tub is 8 1/2" H x 9" in diameter. For ages 12 months and up.
