IOB LEGO® Sets (In Open Box)
IOB means In Open Box: a used set that still comes with its original box. You get the build and the box, usually for well under the price of a sealed copy — especially on retired sets.
Every IOB set is counted piece-by-piece against the official LEGO® inventory before it is listed, so nothing is missing when it arrives.

What does IOB mean?
IOB stands for In Open Box. The set has been opened and built before, and it still comes with its original box.
Is an IOB set complete?
Yes. Every IOB set we list is counted against the official LEGO inventory, including minifigures, so you get every piece.
Why buy IOB instead of new?
IOB sets usually cost less than sealed copies, especially for retired sets, and the original box makes storage and display easier.
