Nervous System 2-in-1 Challenge Purple 350-Piece Puzzle

This 2-in-1 puzzle is designed for the true jigsaw connoisseur. All the usual visual clues have been removed—like our Natural Puzzles, there’s no image to guide you, so you’ll rely entirely on the shapes of the pieces. To raise the challenge even further, we’ve eliminated edge pieces and whimsy shapes, leaving you without the typical starting points for assembly.
