Popular Fireworks Categories

Our showrooms are packed year-round with an incredible assortment of fireworks for celebrations of every size. Here is a preview of some of the most popular product categories we keep in stock at each of our stores so you can pick out the specific brands, shot counts, and effects you want for your show.

Firecrackers These are all about the noise. We stock everything from small individual packs to full bricks and massive rolls containing up to 16,000 firecrackers. For those who want the loudest and most consistent bang, we keep plenty of Black Cat on hand since they are the industry standard for quality.

Bottle Rockets Rockets provide that classic flight and explosion. Our selection starts with standard bottle rockets that whistle and pop, but we also carry large-scale rockets that reach much higher altitudes with bigger breaks. With numerous different sizes, you can choose exactly how much sky you want to fill.

Roman Candles These cardboard tubes fire off a series of colored balls with various effects. While the 5 to 10-shot candles are common, we also stock the larger 100 to 400-shot versions. These heavy-duty candles come with a spike on the bottom so you can secure them into the ground for a hands-free display.

Artillery Shell Kits Often called mortars or reloadables, these give you total control over the sequence of your show. You drop a single shell into the firing tube, light it, and then reload for the next shot. Available in a range of options, from standard festival balls to 60-gram canister shells, which contain the maximum amount of powder allowed for consumer use.

500g Cakes These are the biggest fireworks you can buy without a professional license. Each one is packed with 500 grams of powder to give you a full show with just one fuse. You can choose straight tubes that fire high into the air or fan-shaped cakes that spread the effects across the sky.

200g Cakes These are smaller than the 500g cakes but offer a high shot count and plenty of variety. They’re excellent for keeping the momentum going during a backyard show or for smaller celebrations like birthdays and gender reveals.

Fountains If you want something long-lasting and ground-based, fountains are the best value. They emit a steady stream of sparks with effects like glitter, crackle, and whistles. Since they don’t launch into the air, they are a great choice for smaller spaces or for anyone who wants a show that is impressive but more contained.

Sparklers Sparklers are a favorite for the 4th of July, weddings, and photography. We stock high-quality versions with wooden handles, which are safer to hold and stay much cooler than the typical wire sparklers. They burn slowly with bright and colorful flames and are a great way to get everyone involved in the celebration.
