This set contains a 100 piece puzzle. The number and size of the pieces are designed to allow children from 6 years old to assemble their puzzles, in the universe of their favorite heroes! Searching for pieces, assembling them and rejoicing as the image becomes bigger and bigger – that's what puzzles! That's why kids love putting together the puzzle pieces again and again to create their favorite designs. But puzzles offer so much more than just a game: by reconstructing a puzzle of the right difficulty, kids of all ages take on challenges, learn to become more patient, and build confidence. Everyone will find the puzzle they like from our extensive assortment of Ravensburger children's jigsaw puzzles, ranging from 2 to 300 pieces, illustrated with children's favourite designs. We attach great importance to the choice of patterns and the high quality of our children's puzzles. That is why the safety of all materials is certified by an independent institute. For over 100 years, we have been developing puzzles the way children love them: the pattern, the number of pieces and the size of the pieces are adapted to their age.
