Oxyturbo disposable cylinders

[TheSumOfAllBeers]

I think there is an old thread here where people used to get oxyturbo disposable o2 cyclinders.

Can these still be obtained ? Any stockists that I can find are OOS.

I have all the kit to use these for O2 oxygenation, but cant get the cylinders themselves.

They are available on Amazon uk but looks like delivery to NI only if that helps
