Review on Mudpuppy Dinosaur Glow-In-The-Dark Puzzle, 100 Pieces, 18”X12” –Perfect For Kids Age 5+ - Colorful And Glowing Illustrations Of Dinosaurs And Prehistoric Life - Award-Winning Glow In The Dark Puzzle, Multicolor (9780735345720) by Lori Christensen

I have a dozen mudpuppy puzzles and so far they have all been good quality.The 100 piece glow in the dark puzzles however are not even close to the normal quality I’m used to. First, the quality of the pieces is poor. Several were coming apart and the print was removed. Second, the previous of the cuts of the puzzle pieces is poor. Many would not lock into place. Others were too hard, and many didn’t lay flat.Overall it’s a failure and I’m surprised mudpuppy quality control didn’t catch this before commercialization. I highly suggest you pass and try another puzzle type
