These pillowcases have already proven its worth in the time I've been using them. Upon receiving them, I immediately replaced our pillowcases. They have a luxurious quality that was soft to the touch and velvety smooth. I received these in the middle of a heat wave, and they were very cooling against my face. Speaking of my face, I was thrilled to wake up without creases on my skin and tame hair. I have also experienced bad allergies during fire season and am excited to see how the pillowcases help with the hypoallergenic aspect. For the price and function, I'm super happy with my purchase!
