CXWXC 16g / 25g Threaded CO2 Cartridges or CO2 Inflator for Bike Tires - Cartridge for CO2 Inflator with Threaded Connection, CO2 Pump for Road and Mountain Bikes

Easy to use as any other cartridge. Portable and a solid charge. I used it for an unconventional idea, and uploaded the video. The design worked better than I hoped. Check it out, and you won't be disappointed with the cartridges.

I do alot of ridding and would not be caught without these. I hate pumping up my 26x2.1 mountain bike tires. These are awesome.

Good price, all canisters were full with weights between them varying by less than 2 grams.

I used these for my mini growler and they work just fine.

The 16 gram ones are WAY cheaper than the 25 gram ones gram for gram! Like half the price per gram!!

I bought these for my planted aquarium’s first co2 system, and they fit perfectly! I recommend using 1 bubble per second or the cartridge will run out in less than 6 hours, I’m already on my second one and it hasn’t even been a full day.. but after figuring it out I’m confident that it will last for a little over two weeks! The metal is high quality and sturdy, the threads are as they should be. My plants seem to be responding to this co2 already! I bought this as an emergency replacement after my first co2 cartridge leaked everywhere, and I personally would not buy again as it’s not worth it in the long run.. but this is great if you need co2 on a budge!

Great product. Worth the price

Seem to be quality spare standard CO2 cannisters for my bike pump.
