What supports the Arch? See if you can build it to withstand the tides of water!

Building blocks seem to be regarded as the most simple of toys. That may be true with common blocks, but the Master Builder Sets by HABA inspire your master builder
to design structures that honor creativ ity and imagination. The Master Builder System will appeal to both children and the inner child of every adult. Mix styles to create a structure distinctively your own. The blocks are of the highest quality and will stand up to the test of time, as well as the continued tests of children. Basic size: 2,5 cm; 1 inch.
