The puzzle frame with the contour lines of the puzzle pieces makes it easier to fit them correctly and also serves as a practical puzzle base, even on the go. Everything is included in the frame - age-appropriate puzzle fun with a base. While puzzling, children playfully and enjoyably develop their perception, short-term memory, and logical thinking. In addition, their hand-eye coordination and patience improve. Puzzles with the appropriately chosen difficulty allow children to grow with the challenge, boost their self-confidence, and, above all, provide a lot of fun. The safety of all materials used is confirmed by an independent institute.
