These may be the most expensive wood blocks in the World, and I should know, I searched the globe for a set to amuse 6 grandchildren (ages 1 to 4) for visits to our house. I absolutely did not want lots of tacky, plastic that would end up all over the flat; been there, done that. So, yes, the blocks are pretty much the only toys we have for the kids. Expensive: yes, but also the most beautiful, well-made, endlessly, interesting toy/investment you’ll buy.
