Help Buying sn

[123hopeitspainfree]

Where do you buy sn at in the United States all I can find is ones mixed with salt was between helium and sn but helium isn't a inconspicuous as sn lol and also learned alot of helium is being cut with oxygen now so it's like 20% oxygen 80% helium

You can get other inert gases instead of helium such as nitrogen and argon. Argon would be the best bet for delivery too
