Listen to this article The LEGO House in Billund have switched their 6 Bricks plastic polybags to paper ones! At the attraction you can watch the humble 2×4 red brick being made by the in-house moulding machine. 6 of those bricks then go into a polybag for you to keep as a souvenir when you visit. The difference now is that the packaging has been switched to a paper-based one. This is part of what the LEGO Group are doing to make there packaging more sustainable and environmentally friendly, as more and more sets are shipping with paper bags inside.
