The LEGO Marketing department has given an explanation of the Ultimate Collector’s Series seal on the new LEGO Star Wars Sandcrawler (75059).
“The decision has been made to change the packaging for future “LEGO exclusive” Star Wars sets to include the UCS seal and de-link from the core Star Wars packaging. In addition to the packaging change an update has been made to the building instructions. The building instructions will have additional pages detailing the model’s connection to the movie and its development process. Much as the Creator Expert badge differentiates the larger models from the core assortment the goal of this change is to better communicate to builders that these sets represent our biggest building challenge in the LEGO Star Wars theme.”
