Relentless is a single Ignition compound firework that has 228 x 25mm shots by Hallmark Fireworks that doesn’t let up from start to finish. Starting with a fantastic fanned mine lift to gold and blue stars to vertical star bursts followed by a fan of loud reports, crackling spiders, vivid coloured stars with crackles, mine lifts to brocades and continuing with more relentless barrage of shots into the sky. *FREE WAR HAWKS
