kosztowno

Could you clarify what you mean by "kosztowno"? It could refer to a place name, a term, or something else. If you want a wiki-style article, please specify whether Kosztowno is a real location (and, if so, its country, region, and any available details like population and history) or another concept. If you’d like, I can also produce a concise stub about Kosztowno as a hypothetical place, clearly labeled as such.
