Coming back to school, and with that many people make the material list for the school year ...
I remember I had always news to the children almost force parents to buy ... And this rubber cloud is an example of this, as well to erase all data from notebooks ...
Interestingly, the waste rubbers are like raindrops. Who created it was a German design studio called DFP Design. You can find the rubbers on sale for $ 25 each.
Cool, but not expensive?!
