From amazon, I ordered this one, in 80x40x2, and it came just fine, I also ordered this one, in 120x120x1 and it came all squished to hell. For the larger (120mm) sizes, the packaging is really inadequate, though YMMV. Finally, I ordered this one, in 90x50x1, and it was fine as well. All seemed to be legit.

Darn it's really unforunate, but Gelid just stopped its sale on the 1mm for the one I bought before. This product was $13.99 like a few days ago:

You might have to resort to this:

https://www.amazon.com/Gelid-Solutions-GP-Ultimate-120x20x1-0mm-Installation/dp/B08PKQFT2P/ref=sr_1_4?dchild=1&keywords=gelid+ultimate&qid=1626549982&sr=8-4

But that second one is a bit too thin being only 20mm in width.

If you're in the US here is also one that I would recommend:

Per $/sq mm it's really affordable right now.
