This 105 Piece Building Block Set is made from hardwood to a standard 1.375" (35mm) width. Each piece is dimensionally accurate, making building and leveling easy. THESE ARE BIG BLOCKS - definitely not a choking hazard. This set differs from our other Block Set - many pieces are curved, cylindrical, arched or triangular; but there are many blocks as well.
Dimensions: Various, but all have a width of 1.375". (See illustration).
Hand sanded on all sides and corners for a wonderfully smooth feel - these are safe and splinterless. Over 40lbs of building and early math discoveries! Pair it with our 65 Piece Building Block Set (M125) for a truly awesome collection.
