1. Baby Safe Fabric: Our Nursing Pillowcase is made of super soft high quality Minky Dot fabric with a unique weaving and bristle process, which is gentler, softer and more comfortable than regular fibers. Soft, breathable and hypoallergenic to baby's skin. Soft, breathable fabric won't irritate your baby's skin. 2. Hidden zipper protection: The zipper is covered, so no matter which side of the breastfeeding pillowcase you use, your baby's skin will never touch the zipper. It's also durable enough to pass through regular washing. 3. Stylish Design: Nursing pillowcases are specially designed for feeding pillows and baby support pillows and other pillows of the same size. With our designs, you get style and function from every nursing pillowcase. 4. EASY TO CLEAN: It's also machine washable, so whenever your little one gets dirty, you can easily wash it off in your regular wash cycle.
