CO2 canister replacements

I always carry one along with a pump, and manage to get through about one a year. Buying in bulk sounds attractive, but you probably won't need as many as you think.

Decathlon do cheap ones, I think.

Ahh, laughing gas. So much fun to be had.... think I'm a bit too old for it these days. Still, probably far less bad for you than having a few beers.

If you want a real laugh, check out the mail restrictions for international... it includes "items made of a cellulose pulp" - like say "paper"...

In fact about the only thing you can send is railway rolling stock (except it has to be under the weight limit - so a really really lightweight railway carriage)

Be very careful if they are set via Royal Snail as they treat them as explosives and confiscate them.

Box of 30 threaded 16g cartridges from www.co2cartridges.co.uk for a smidge under 25 quid...

Heck of a lot more reasonable than 2 for £7 locally.

You can get them in bulk packs 30 or more very cheaply. Now the problem I had was the diameter difference on the neck from the original cartridge and new bulk delivery items were slightly different and wouldn't fit. But I decided to open out the holder casing ever so slightly. Worked a treat, I have enough stock of co2 for a few years if not more. But it doesn't matter for the next 3 months, as I have broken my foot

It's more likely that the empties you see at NO2 that kids have been huffing. It's a big problem and I see loads in Bristol.

You can buy them on Amazon or ebay, threaded ones are used for cycling and air guns and you can find them cheaper for shooting than you would at some bike shops.

Myself I bought a load in bulk when they were on cheap somewhere
