Our Toddler Block Set features five unit block shapes selected because they are perfect for small "toddler-size" hands!  Each set includes 20 hard maple blocks:  6 - 1/2 units, 2 - units, 4 - unit flats, 6 - 1/2 pillars and 2 - pillars.  Blocks are still based on the traditional unit block dimension of 1-3/8"  x  2-3/4"  x  5-1/2".  Beka's unit blocks are all fractions of or multiples of that basic unit.  Item # 06020.
