Fast U.S. Shipping on Every Order
All smoke products ship hazmat ground from our U.S. warehouse. No customs delays, no air freight restrictions.
Smoke grenades are classified as hazardous materials. We are legally required to use a certified hazmat courier (FedEx or UPS) for every shipment. We don't set this price — the carriers do. We don't profit on shipping; we often lose money on it. Anyone shipping smoke bombs cheaper is either absorbing the cost or doing it illegally. Non-compliant shippers risk a $500,000 federal fine for improper hazmat shipping. We prefer to do it right.
💡 Best value tip: The more you order in one shipment, the better your per-unit cost. $125 minimum order. Order $225+ and shipping is on us — plus you unlock up to 4 free smokes along the way.

Frequently Asked Questions
What if my smoke bomb doesn't work?
Every product is 100% guaranteed. If a grenade is faulty you choose: store credit at 1.5× the unit price (a $64.98 pack = $97.47 credit, auto-applies at checkout, never expires) or an exact product refund. Note: shipping costs are not refunded for individual product claims — the guarantee covers product cost only. Email hello@shutterbombs.com with subject Guarantee Claim – Order #XXXX + a photo/video. Processed in 1–2 business days.
Are your smoke bombs safe to use around people?
Yes — all Shutter Bombs products use Enola Gaye's non-toxic cool-burn formula. The smoke is produced without open flame and burns at low temperatures. CE and CPSC tested. Use in well-ventilated outdoor spaces and avoid extended inhalation.
How long does the smoke last?
Burn time varies by model: EG25 ≈ 30 seconds · Twin Vent II ≈ 25 seconds (intense dual-vent burst) · WP40-D ≈ 60 seconds · TP40 ≈ 60 seconds · WP40 ≈ 90 seconds. For photography, the 60–90 second models give you enough time for 30–50 shots in a fast-paced session. The Twin Vent II trades duration for density — it dumps its charge from both ends simultaneously for maximum visual impact in a short window.
What's the difference between wire-pull and top-pull?
Wire-pull grenades (WP40, WP40-D, Twin Vent II, EG25) activate by pulling a ring away from the body — great for one-handed use. Top-pull (TP40) is activated by pulling the top cap upward. Both ignition systems produce the same dense smoke; it's purely a preference of activation style.
Can I use these indoors?
We strongly recommend outdoor use only. In enclosed spaces, smoke concentrations can build quickly and trigger fire alarms. If you must shoot indoors, ensure full ventilation, disable smoke alarms in advance, and use only one grenade at a time with all windows/doors open.
Do they expire? How long can I store them?
Enola Gaye smoke grenades have a 10+ year shelf life when stored in a cool, dry location away from direct sunlight. Sealed products are stable and reliable well beyond a typical shooting season.
Why is shipping so expensive?
Smoke grenades are federally classified as hazardous materials, which means we are legally required to use a certified hazmat courier (FedEx or UPS ground) for every order. We don't control this rate — the carriers do. We don't profit on shipping and often lose money on it. Anyone shipping smoke bombs for less is either absorbing the cost or doing it illegally (risking a $500,000 federal fine). We ship to all 48 contiguous U.S. states. Alaska and Hawaii not currently available.
The best way to offset the shipping cost is to order more in one shipment — orders over $200 ship free.
Where can I find the Safety Data Sheet (SDS) for these products?
Official Safety Data Sheets (SDS/PSDS) for every Enola Gaye smoke grenade we carry are available on our Safety & Compliance page. These documents are published by Enola Gaye and include full chemical composition data, handling instructions, and emergency procedures. If you need an SDS for a venue approval, insurance filing, or event permit, you can download the PDF for each specific model directly from that page.
