This box contains a 100-piece puzzle. The number and size of the pieces are designed to allow children from the age of 6 to assemble their puzzles in the world of their favorite heroes! Searching for pieces, assembling them, and delighting in seeing the image grow larger and larger - that's what doing puzzles is all about! That's why children love assembling puzzle pieces over and over again to create their favorite designs. But puzzles offer much more than just a game: by putting together a puzzle of the right difficulty, children of all ages take on challenges, learn to become more patient, and strengthen their self-confidence. Everyone will find the puzzle they like among our wide assortment of Ravensburger puzzles for children, ranging from 2 to 300 pieces, illustrated with children's favorite designs. We place great importance on the selection of designs 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 that children love: the design, number of pieces, and size of the pieces are adapted to their age.
