Slip spent over 10 years perfecting its signature pillowcase that helps prevent ageing and damage caused to skin and hair by cotton covers. Made from premium mulberry slipsilk™, it has a smooth, lustrous surface and a low absorbency rate, so bedhead, sleep creases, and dryness will be a thing of the past. If you're looking to complete a set or give a gift, it's also available in black, white and charcoal.
