I had to buy other geomag color boxes in order to make important structures. With 216 + 86 + 64 pieces, we can finally start doing some interesting figures. With an engineer friend, like me, we enjoyed more than my money small, a whole afternoon: Beautiful self-supported structures, cantilevers, trellis bridges ... To initiate our little darlings, this box is nice, but the box is, the greater the quantity / price is interesting.
