12 Gram CO2 Cartridge for Airsoft and Air Gun (Quantity: Case of 100 / EMG)

"Its CO2, but it has some issues
Pros:
Shiny
Works in cold environments
12g

Cons:
Out of 3 different orders of this one had co2 that barley had enough gas for 1 mag that normally got 3-4x more.

It's great co2 for the price and well worth it, just make sure to test your mags when you add the co2 to make sure it works.

"The Co2 cartridges are cheaper here than at walmart, but only by $1. The only reason i bought it here is because i ordered a Co2 pistol and i didnt want to go to walmart. The only reason that i gave it 4* is because walmart also sells them in 25 packs with an actual box. When i bought it, the cartridges were spread out on the bottom of the box without any packagind.

"The packaging is the only complaint I have. It just seems like they put no effort into these cylinders. They only came in plastic resealable bags. They work fine though, about 6 mags in my ASG TAC6.
