Will thease work good in a warehouse freezer writing on paper

Yes they do I have worked with them outside in the extreme cold outside

Does the ink fade, or is it archival quality and good for checks etc.?

I have used these pens for years and love them. I have never had any fading problems. But, I can not state that they are 'archival quality' But, I do love the pens, and I have papers 2-4 years old with no fading.

Are these 0.7? Description says they are, but picture shows 0.5.

Of the pictures shown only one is showing up as 0.5 and it won't allow me to zoom in. I believe it might be an error showing the wrong pen. The other clear picture, that's zoom-able, is clearly showing 0.7. I don't recall ordering any 0.5 pens. I only have the 1.0 and 0.7 sizes. I still have a few dozen pens left. They never stop working until they completely run out of ink. I prefer the smoother 1.0 size personally. The 0.7 is great for when I need clear precise writing in very small spaces. Great pen!
