The Jake's Fireworks American Muscle Fireworks Assortment is a large, value-packed fireworks variety pack sold exclusively at Costco warehouse locations. Weighing approximately 19 pounds, this substantial assortment is produced by World Class Fireworks under the Jake's Fireworks brand and delivers a wide range of aerial and ground effects suitable for backyard Fourth of July and patriotic celebrations.

The American Muscle assortment is designed for variety, bundling multiple firework types into a single box so buyers can run a full show without purchasing individual items. Typical Jake's/World Class assortment packs of this size include aerial repeaters (cakes), artillery shells, fountains, roman candles, and ground spinners. Effects commonly featured in Jake's assortments include color bursts with gold glitter, red, green, and blue with brocade crowns, and mines with whistling tails. The 19-pound gross weight reflects the combined weight of all included items and packaging.
