Why is LEGO Space Accessories (Exploriens) so expensive?
Space Accessories (Exploriens) was released in 1996 and has since retired. Once LEGO stops producing a set, the only supply is what is already in circulation, so sealed copies in good condition compete for a shrinking pool of stock. That scarcity, not the parts, is what moves the price.
