Just wow! I love these pillow cases! I purchased one for my severely asthmatic 9 year old and one for myself, and we’ve both had a great nights sleep. Over a few days I’ve noticed we’ve woken up more refreshed than usual. Our hair and skin is amazing. I believe it’s also helped my son with his chronic dust allergy. I’d love to get more for the rest of our family. Thanks kudd.ly™ !
