These Glacé pillowcases are crafted from lustrous 25 momme Mulberry silk, chosen for its radiant sheen and incomparable smoothness. Naturally gentle on skin and hair, they help prevent creasing and frizz while keeping you cool through the night. They are finished with a discreet envelope closure for an elegant look. Also available in Glacial Green. We always recommend hand washing our silk bedding, but it can also be machine washed at 30 degrees celsius or lower on a delicate cycle. For small items, use a fine mesh washing bag, and always use washing liquid and fabric conditioner made specifically for silk, to maintain its beautiful lustre. Make sure to line dry the silk bedding as it is not suitable for tumble drying. Silk 100%
