About Underwater Loop

Underwater Loop (41337-1) is a LEGO Friends set released in 2019, currently averaging $11.55 used on BrickLink. It comes with 2 minifigures worth a combined $3.25. The set has retired from retail, so secondary market is the only option. The full parts inventory runs 158 pieces.

Part-out value

The minifigures account for about 28% of the set's value ($3.25 out of $11.55). The remaining value is in the parts and the set as a complete package. Selling complete will likely net more than parting out unless you have specific demand for the individual figures.

Seller notes

  • Sealed copies sell for $27.27 vs $11.55 used — a 136% premium. If you have this set new in sealed box (NISB), price it accordingly.
