My daughter got the building blocks for Christmas. At first we were totally thrilled. The stones have beautiful colors are varied and thus of course interesting for a long time. Unfortunately we had to find New Year's Eve, that the great colors come off of the stones (especially yellow, red and orange). Namely, no shocks (the stones tolerated very well), but by licking. In my opinion, but toys should be painted for small children with saliva solid colors. Especially with "high-quality brand products". Bad enough that the color goes off and after just one week!
I Haba asked directly to give an opinion, if the problem with the colors is known. Unfortunately, my request was not answered.
My review also coincides precisely for these reasons, unlike previous speakers bad. For the high price, I expect better quality and customer service. Since Haba my knowledge not produced in Germany (one may like to correct me) is anyway questionable whether the stones that price is really worth.
