Slip pure silk sleep masks are 100% pure silk, inside and out. They're made with pure silk filler, silk internal liner and a silk-covered elastic band. Beware of cheap imitations.
Slipsilk is specially-commissioned and made to our exacting standards, developed and refined over ten years to provide the ultimate combination of shine, thickness, softness and durability. We use the highest grade (6A) long fibre mulberry silk, with a thickness of 22 momme and enforce the strictest quality guidelines, including non-toxic dyes.
