20 pack 12 Gram Unthreaded CO2 Industrial Gas

only quirk was the tips dont screw in, you have to know exactly what you are buying the tanks for they don't fit every gun

These cartridges were very specific for the device that requires them and I was able to find them at Walmart.com. The only reason that I gave it 4 stars instead of 5 is because of the fact that I only needed 3 to 5 and I had to buy 20. It wasn't as much about the price as it was the fact that I had to buy so many but only needed a few. It showed up as 2 boxes of 10 and they were independent of each other. So, they put 2 boxes of 10 in a package when one box would have been more than enough. Now I have to figure out where to store all the extras. The device only uses one at a time and it's a safety device that is water activated so I may even wind up using one out of 20, unless there is an emergency and it gets used. Other than that, everything is great and I'm very happy I was able to get them from walmart and have them delivered.

they work well with my older keg charger altho Im using them for home made 2 liter bottled pop. these may not fit the newer chargers. if whatever you have requires 12 gram, screw on co2 cartridges these are them.
