Food / Polish Salted Butter [57]

Hi not being Polish but trying to learn all about the Polish cuisine.

There is a small Polish shop right next to me and i love going in there and getting different slices of meat i also bought some butter but i don't think it's a salted variety as it does not taste like the butters i usually get.

Is there any specific butters that are like the salted butters i am used to ie lurpak or salted Scottish butter. Thx in advance
