This box contains a 150-piece puzzle. The number and size of the pieces are designed to allow children from age 7 to assemble their puzzles in the world of their favorite heroes! Searching for pieces, putting them together, and delighting in seeing the image grow larger and larger – that's what puzzling is all about! That's why children love assembling the puzzle pieces again and again to create their favorite patterns. But puzzles offer much more than just a game: by piecing together a puzzle of the right difficulty, children of all ages face challenges, learn to be more patient, and build their self-confidence. Everyone will find a puzzle they like among our wide range of Ravensburger children's puzzles, from 2 to 300 pieces, illustrated with children's favorite themes. We place great importance on the selection of themes and the high quality of our puzzles for children. That's why the safety of all materials is certified by an independent institute. For over 100 years, we have been developing puzzles as children love them: the theme, the number of pieces, and the size of the pieces are adapted to their age.
