This is a premium, artisan-style dried pasta from the Polish brand Czaniecki. "Square shaped" likely refers to pasta shapes like quadretti (small flat squares) or maltagliati (irregular flat pieces), often used in soups, broths, or with light sauces. Made with high-quality durum wheat semolina, this shape emphasizes a delicate texture and traditional craftsmanship, ideal for simple, homestyle dishes.
