These organic cotton percale pillow cases are great if you have allergies. The organic cotton is soft and washes well. Make sure to dry them on low heat or they will wrinkle and it will be hard to get the wrinkles out. I ironed mine after getting it too hot, and the wrinkles still didn’t come all the way out. I had to rewash it and make sure it was on low heat. They are soft and look really nice on.
