Can you use Steam Steam Gift Cards from other countries?

I would like to buy a Steam Gift Card on Amazon. I do not know if I can use this as there's no country (like psn or Xbox voucher cards) so you can use them in every country? (come from Italy)

These, for example, you can also use in Italy. [https://www.amazon.it/Steam-Gift-Card-50-Valve/dp/B00HJBPZK8/

Actually only in the respective country. But because you do not know that, maybe you should buy it in a shop like: rewe, Mediamarkt, aldi etc

Thanks a lot!

Steam credit codes can be redeemed in every country.
I'm releasing my € penny cards in my Argentine Steamaccount without any problems. The value is then automatically converted into shop currency. Lately even better than the daily rate.
