Boxed in Polish would be: "Boxed" as a standalone word might translate to "Z pudełka" or "Opakowane" depending on context. Since the user provided only "Boxed" with no context, translate as a label likely used in product condition. The standard translation for a product listing condition "Boxed" is "Boxowane" or "Z pudełka". For accuracy in marketplace, use "W pudełku". However instruction says preserve line breaks and paragraph structure; single word so just translation. I'll choose "W pudełku".
