Sleep Mask - Black

Slip® products are made with Slipsilk™ – a premium, 100% pure mulberry silk that offers the perfect balance of softness, shine, and durability. Scientifically tested and made from the highest 6A grade silk with a 22 momme thickness, it adheres to the strictest quality guidelines. It is shown to reduce friction by 43%, helping to prevent sleep creases and minimise tugging on delicate skin. Its smooth surface absorbs less face cream, allowing your skincare to stay where it’s needed and work properly. Hair stays smoother too, with reduced tangling and frizz, giving you the ultimate beauty sleep experience.

Founded in 2004, Slip® revolutionised beauty sleep. It all began when co-founder Fiona Stewart, struggling with sensitive skin, wrapped her pillow in the finest silk she could find, resulting in immediate and dramatic benefits. Partnering with Justin Dubois, Fiona created the first silk pillowcase marketed as a beauty product. Today, Slip® offers much more than pillowcases, with a range of luxurious silk beauty essentials designed to care for skin and hair. This family-owned Australian brand has won over 130 awards and supports global charities, proving that beauty and kindness go hand in hand.

CARE:

Handwash (recommended) your slip® sleep mask with gentle pH neutral liquid detergent (or fabric softener) to maximise its life span and help to keep its shine, softness and ‘slip’. Never place your slip® sleep mask in the washing machine.

When it comes to drying your slip® sleep mask natural air drying in the shade is best. Do not tumble dry.
