My kids love puzzles, this one is ideal for 4 in the same box puzzles, 4 difficulty levels, on the back of ièces recognizable by a symbol. Once distributed in individual bags, children can play easily. But big big big downside but not least: it lacks a piece of puzzles, inadmissible. I saw in the comments that a customer had encountered this problem, and although we are at least 2. FYI I also bought one of the fairies and the 4 puzzles are complete!
