Do not buy! Dangerous! Wood from splintering!

I bought this puzzle for our baby because it had so much fun on a similar wooden puzzle in the toddler group.
At first everything was fine, the puzzle was a real favorite toy.
After 5 weeks, in use, with games and ansabbern I have it thrown away now. At all edges of the puzzle pieces to solve splinters! Total dangerous!
The fact that the color does not keep them too, of course ... But splinters're really the last!
Very poor quality!
