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 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!

In these days of high volume mountain bike tires, why would anyone want a smaller cartridge? Buy these!

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

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.

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

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

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