First up, a collection of kits from a galaxy far, far away will retire at the end of 2021. Two of our favorites are Darth Vader's Castle and Kylo Ren's Shuttle, both of which are some of the enticing builds from the LEGO Star Wars lineup.
Plenty of builds from the Marvel universe are also set to retire, Though our favorites have to be the Iron Man Hall of Armor or the Avengers Tower Battle, both are display-worthy additions to your collection that won't be around much longer.
Over in the Wizarding World, plenty of Harry Potter sets are slated to retire. While the Grand Hall is an easy highlight, there are plenty of other kits packed with witchcraft and wizardry to score before year's end.
Several fan-inspired sets from the LEGO Ideas stable are being retired, including Dinosaur Fossils, Pirates of Barracuda Bay, and more.
There are over 100 different sets from the LEGO collection that'll retire by year's end. So if there are any that catch your eye, now's the time to add them to your collection before they disappear forever.
