I remember getting my first pair of real jeans there
Yes, me too. They were like 8 or 10 dollars, but at that time, right after I finished high school, my salary was about 2000 zloty which was only $20 USA. Meaning, my jeans cost me a half of my monthly salary! :)... but I HAD to have them!
The small Pewex was inside of a hotel - right across from the train station in Kielce.
It smelled beautiful inside and the bath soaps felt like heaven.
