Brickheist's take
A large Icons display model of a tropical aquarium, at over 4,000 pieces a substantial build aimed at adult fans. Rather than a playset, it is designed as a decorative centrepiece, with brick-built marine life and scenery doing the work that minifigures do in other sets. It is one of the more unusual subjects in the recent Icons line-up.
Discounts have been modest so far: today's cheapest price is less than a tenth below RRP, though that is also the lowest we have recorded. Only four shops we track stock it, so compare shipping. Newer large Icons sets often see deeper discounts later, so an alert may pay off.
