For ages 2+ years. For ages 2+ years. At 18mm thick, these are our chunkiest chunkies ever! Each 15-piece puzzle is a play set, too: Place a top, middle, and bottom for each space in the wooden playboard to create over 100 possible characters, from a ballerina with a mermaid tail to a fairy wearing a bridal veil. Or remove the pieces from the board to stack them upright, and add even more creative possibilities! The sturdy wooden pieces are easy for kids to grasp and stack, nurturing fine motor skills, hand-eye coordination, and imagination, too.
