These navy blue polyester napkins are great for all kinds of special events like weddings and parties. To use them, just unfold and place them on the table. They're stain and wrinkle-resistant, so you don't have to worry too much about spills or creases. When it's time to clean, wash them in warm water and dry at a low temperature. This will keep them looking nice and new for a long time. Avoid using harsh chemicals or high heat, as it might damage the fabric.
