Geas PRIMA bricks 2x4

After loaning tools from LEGO to make Automatic Binding Bricks, Geas started making their own bricks and sets known as PRIMA. The bricks are made of a sturdy plastic similar to the thick 700e LEGO plates, and came in a variety of sizes and colours.

The PRIMA sets only included basic 2x4, 2x2 bricks and windows/doors in the colours red, yellow, green and white. Other kind of parts and bricks in other colours had to be bought seperately.
