Sluban Water-Tank Fire Engine Brick Building Set (M38-B0626, 343 Pieces) - Red

What you're getting

Build yourself a proper fire engine with this Sluban water-tank lorry set. You get 343 pieces to construct a red fire engine complete with a water cannon — the sort of thing that'll keep your kids occupied for a good while, and then they've got an actual toy to play with afterwards rather than a pile of bricks gathering dust.

It's the kind of set that works for emergency rescue role play, which means you might actually get five minutes' peace while they're sorting out imaginary disasters.
