Deep navy has a way of grounding a room and inviting rest – midnight blue that feels calm rather than cold. In pure mulberry silk it's rich and tactile, the kind of colour you sink into at the end of a long day. The silk itselfWe use 22-momme, 6A-grade mulberry silk, the finest you can buy. Momme is how silk is weighed, and 22 is the number to look for: dense enough to feel substantial and drape beautifully, yet able to wash again and again and still feel new. Both sides are pure silk, never blended. Kind to your skinUnlike cotton, silk barely tugs at your skin or wicks away moisture, so mornings arrive with a calmer, fresher complexion. Kind to your hairIf you've ever woken to a tangle, your pillowcase may be the culprit. Cotton's rougher weave catches all night; silk lets hair slip freely, for less frizz and less breakage. The detailsA reinforced hidden zip keeps the pillow tucked neatly out of sight, and each pillowcase arrives individually boxed – ready to give, or to keep. Made safelyIt carries OEKO-TEX Standard 100 certification, which means it's been tested for harmful substances – nothing on it you wouldn't want near your face each night.
