LEGO Window Exploration Bag: FAQ

Is the LEGO Window Exploration Bag retiring?

Not yet flagged, but the LEGO Window Exploration Bag is an older set. LEGO.com UK doesn’t list it as “Retiring soon” yet, but it has been on sale since 2010, longer than most sets (two to three years). That makes it one of the likelier sets to be flagged next. We check every day and will update this page the day it is.
