4 Pcs (Green, Yellow, Blue, Red) color smoke for photography, Emits Colored Smoke for 50 Seconds

These smoke bombs are simple to use, just have to remember to pull the ring sideways and not directly up. The smoke was nice and vibrant and lasted around 45 secs. Makes a huge cloud if there's no wind. Overall a good product.

Literally a smoke bomb like you can buy for $2 close to 4th of July. Nothing special, not nothing different than a large canister smoke bomb.

I bought these for a Photography Club project at my school. Three of the four bombs popped when the ring was pulled and you could smell the "burn" but no smoke came out. Becuase the rings came all the way out when pulled, there was nothing else to do (we even tried lighting them with matches, and nothing.) The one that worked (blue) was beautiful and gave off lots of good, vibrant smoke. But the purchase was a disappointment, especially because students had been looking forward to this project.

These are really cool, the pull string makes them easy to use.
