London Underground

Take a wild ride through the skies with London Underground, Hallmark’s explosive barrage pack inspired by the speed, power, and energy of the capital’s iconic tube system. This underground-themed pack brings overground thrills — with a carefully curated selection of high-impact barrages that fire in rapid succession, just like a train storming through the tunnels.

Expect intense bursts, sky-filling effects, thunderous crackles, and a vibrant display of colour that would make even the London Eye blink twice.
