The positives are a small optimized storage box to save space, with 4 compartments do not mix puzzles, and a small design on the back of parts do not mix. The cover is simple wood with an edge which allows it leave a decoration puzzle as shown in the photo above, rather than breaking everything immediately and store.
The puzzle pieces are thick, and are more like pieces of a puzzle adult as pieces of a puzzle child, which makes it a good puzzle "transition".
From the perspective of the evolution of the child, do a puzzle remains an excellent exercise in motor skills, concentration and reflection.
Finally, the price is unbeatable with 9.99 4 puzzles or 2.5 euros the puzzle.
Only complaint, the models are drawn on the little box, so not at all used by the child.
In conclusion, a very good value, well-designed puzzles, solid and convenient storage. A level of difficulty a little high for 3 years, but a good opportunity to play with parents.
