Perfect gift for Dinosaur fans aged 36 months plus. A large puzzle, approx. 7.6 x 24.1 x 30.5 cm or 3ft long, comprising of 48 super sized, thick, sturdy pieces that are both easy to hold and easy to assemble. My grandson, three years, can now just about put the puzzle together by himself and never seems to tire of it. The giant T-Rex has lots of detailing and an almost 3D effect once completed. A solid puzzle that takes some serious wear and tear without harmful effects and is regularly shoved and pushed around the floor. I use a slightly damp cloth to wipe on the picture side of the pieces if we have any spills. We have several of the Melissa & Doug giant floor puzzles and this is possibly my favourite. My grandson would agree. Happy to recommend. I really like this T-Rex.
