Mammoth by name, mammoth by burn time. These 18-inch sparklers from Bright Star give you a solid 60 seconds each — long enough to actually write your name, take a photo, and still have time left over.
Pack of four, F1 rated, so they're cleared for indoor and outdoor use. The longer length means they stay cooler at the holding end for longer, and there's more sparkler to enjoy before you need the bucket. A proper step up from the standard 10-inch ones that fizzle out before you've finished spelling "happy."
