The set is one satin case with one sleep mask.  The satin pillow case cover is perfect for travel and slips right on top of your large pillow with ease. It’s perfect for those occasional nap caps.Use it when recovering from surgery, traveling away from home or as a alternative to the bonnet .Many are not bonnet wearers but the hair still needs protection. Especially curly hair. Cotton pillow cases absorbs hair moisture leaving us with dry brittle hair. This is why you should opt to use a satin or silk casing instead. Plus it’s cute, so the bae probably wont complain about this lavish accessory.
