LEGO Exclusive / LEGO Internal Sets

LEGO Internal Sets are specially produced sets not intended for commercial sale but for internal use within the LEGO Group or as part of specific events or promotional activities. These sets often serve purposes such as employee gifts, event giveaways, or corporate gifts and are generally not available to the public. Examples include sets given to employees during holidays or milestone anniversaries and those created for special events like LEGO conventions or partnerships with other companies. Due to their limited production and unique context, Internal Sets are often highly sought after by collectors.
