Originally, I had (foolishly) overlooked this Grimm's gem. But when family got it for us as a Christmas gift, we were all delighted. Not only is it a GORGEOUS puzzle, the pieces make for amazing stacking and challenges just like the infamous traditional rainbow stackers. It's so much more complimentary than I'd thought at first glance, and it quickly became one of our favorite pieces.
Can not wait to give this to my kids for Christmas! Perfect colors and high quality.
