It's easy to create fun puzzles that pop! Complete the two 24-piece outer space and dinosaurs jigsaw puzzles, then fill in the colour-coded pictures with a matching coloured marker (markers not included).Use the included 3-D glasses to transform the puzzles into multi-dimensional scenes.When filled in, warm colours like red and orange will come forward, while cool colours like blue and green recede into the background, giving a 3-D look! Kids four and older will love putting together the 3-D jigsaw puzzles over and over.
