When the contract between Geas and LEGO ended, Geas started making their own bricks and boxes known as PRIMA. The ABB bricks were made using two different plastics as seen on the picture below. A shiny slightly translucent plastic, and the more well known CA (Cellulose Acetate) plastic on the bottom row:
