The Bigbox distinguished by the fact that it combines the basic version, 3 big extensions and some minor enhancements in a box. The box looks quite large, however, ensures order in the "Kätchenchaos". There is for each extension a corresponding recess for stowing. In the lid of the box is a "legend" for filling the cards holder stating how many card has any extension, thus you can check if a card is not yet even gone under the table always easy.
