Magnetic creativity to share with your kids

I must admit this is probably more something for big kids and most likely for creative moms. A few weeks ago I was shopping with my sister (mother of 2 little boys) and she pointed out to me that very often we like design type toys and kids prefer the most bold colors, cheapest plastic material and ugliest design. Never the less. I would feel it is my obligation to at least try to introduce them to well shaped toys that help them develop and that are a lust of my eye! Such as these TATLIN cardboard magnetics by Kidsonroof from the Netherlands. There are three different type of sets: Tatlin Big, Archetype cars & boats and Archetype buildings.
