I took the 500 pces and it is very hard since peaces are pretty small and have unusual puzzle shapes. Also alot of them or all black, all white, all grey so it can be hard for young children. Nevertheless, my son was very happy about its Florian Wirtz's puzzle and keep working on it.
Wasn’t entirely sure it was a legitimate product but it is! The detail of the puzzle is amazing. The pieces do not ‘join’ when placing together so they move around a bit which was difficult for our 8 year old. Delivery took some time, but the quality is good.
