Is LEGO Underwater Loop retired?
Yes — Underwater Loop (41337-1) has been retired by LEGO and is no longer in production. Retired sets have fixed supply, which is why their prices are driven purely by the resale market.

What is the price per piece for Underwater Loop?
At its $30 retail price across 389 pieces, Underwater Loop works out to about $0.077 per piece. Collectors often use price per piece to judge whether a set is good value.
Is LEGO Underwater Loop a good investment?
Underwater Loop currently trades 15.9% above its $30 retail price, and it is retired, so no new supply is entering the market. Past performance is not a prediction — condition, packaging and how long you hold all affect what a set actually sells for. BrickStats reports the numbers rather than giving investment advice.
Why is LEGO Underwater Loop so expensive?
Underwater Loop was released in 2019 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.
