The reason we bought these sheets is because the fabric is GOTS certified organic cotton and OEKO TEX certified free of harmful chemicals, it’s hard to find products with both certifications. But then, Blaynk takes clean to a whole other level by not using any chemicals at all! WOW, that is so rare, thank you! The sheets are very comfortable. They feel like nice hotel sheets. Very good quality. And we sleep in comfort, knowing that at least for the hours we are sleeping, our skin is not absorbing toxins. I also had a great experience with Blaynk customer service when UPS failed to deliver one of my items. Just a wonderful company and product!
