Selling a sealed International Space Station?

International Space Station — common questions
How much can I get for a sealed LEGO International Space Station (21321)?
We pay up to £45 for a factory-sealed 21321, with free postage and payment within 2 days of it arriving. Our offers track recent sales, so they move with the market.
Is International Space Station worth more sealed than opened?
Yes — our sealed offer (£45) is about 73% higher than for a complete, opened copy (£26). If yours has never been opened, select New & Sealed for the higher price.
Is LEGO International Space Station retired?
Yes — 21321 is no longer produced by LEGO, so sealed copies only become scarcer from here. Retired sets in sealed condition are typically our strongest offers.
Do you buy 21321 with a damaged box?
Yes. Shelf wear, a dented corner or a small tear still counts as sealed as long as the set has never been opened. If the seal is broken, choose Complete instead and we'll price it as an opened set.
