It's a Polish brand axami.org Probably pronounced the same as English. 'Aksami' doesn't look as good, but the connection is obvious for Polish speakers. Looking at the website, it's obvious why they want an x.
I see a polish brand call "axami" how do i pronounce that?
Ah-KSAH-mee. The company name is based on the Polish word "aksamit", which means "velvet". The "x" is just for catchiness and exoticness. As mentioned above, "x" is not a Polish letter, though most people would know that it's pronounced "ks" in English, especially those in the target demographic.
