Countdown to Christmas with this unique Jigsaw Puzzle Advent Calendar. Enclosed are 24 numbered boxes each containing one section of the puzzle. Beginning December 1 assemble the pieces in the box numbered “1”. Assemble the pieces in the next numbered box each day through December 24 and the puzzle will be complete for Christmas! A bonus poster is included to help guide assembly. The pieces on the back of each puzzle are numbered 1 through 24 making it easy to distinguish the pieces in each section. When the season ends simply break the puzzle apart and put the pieces in their respective boxes for more fun next year. All of our jigsaw puzzles are produced on thick premium quality board and made with recycled materials. Precision cutting results in minimal dust. Our randomly shaped pieces are fully interlocking to ensure the best possible puzzle building experience!
