Interlox Squares - 40 Piece Set

My three-year-old figured out the clip edges on his own within five minutes, and now he’s building little people instead of just stacking blocks. The pieces are sturdy enough that he can snap them together and pull them apart without me helping, which makes it a win for independent play.

The easy-clip edges make it simple for my 3-year-old to snap pieces together without frustration, and we've already built a castle and a robot in one sitting.

My 4-year-old finally stopped chewing on the pieces and actually started connecting them — the easy-to-clip edges are perfect for his little fingers. We've already made a robot and a tower that wobbles but stands.
