Little compares to the joy of opening a box of Lego and spilling the contents onto the table, ready for construction.
But Lego is among the most collectable of toys, with the rarest sets and minifigures fetching many thousands of pounds.
That’s why people often buy it as an investment for themselves or their children, with the sets sitting pristine in their wrapping.
While it’s true that unopened Lego sets are usually worth much more, well-loved ones can still fetch a pretty penny if they’re rare enough.
