Dora the Explorer 24-Piece Jigsaw Puzzle, A Set of 4 Puzzles

Even though these are made of thick card board, they are ALL warped which makes putting a puzzle together extremely impossable. Just when she would get 2-3 pieces put together the others would pop up with uneven surfaces. I had to do them with her so I could bend pieces so they would stop popping up. She was so frustrated with the pieces that she finally just used the puzzle for confetti. I Would NOT buy this brand again, too bad because my daughter really liked the Dora pictures but what a waiste of money! I don't know how "Melissa & Doug" or "Ravensburger" make puzzles that are sooooo flat, no curling of edges and have been played with a lots of times and still look awesome everytime my kids put them together. I wish a puzzle was a puzzle.

The majority of puzzle pieces are warped and I will be returning. The piece are difficult to put together and come undone when you put a piece next to it together. Says Under license by Cardinal Industries Inc.

The puzzles are fun and challenge enough for my daughter. But the cardboard material is too soft after a few uses, and it's too thin.
