22 Momme Ivory King Size Silk Pillowcase 100% Mulberry Silk
Description
This is the king size of our warm ivory silk pillowcase — 50 × 90cm, the larger cut made to fit a UK king size pillow. Same 22 Momme, grade 6A Mulberry silk as our standard size; just more of it. Need the smaller 50 × 75cm? See our standard Ivory Silk Pillowcase. Made from 22 Momme, grade 6A long strand Mulberry silk: the smooth, substantial weight that's kind to hair and skin, and strong enough for the washing machine.

Is the king size the one you need?
This is the larger of our two sizes. At 50 × 90cm (20 × 36") it's made for UK king size pillows — the long ones — and it's the size to choose for super king and emperor beds, where two sit side by side across the width.
If your pillows are the everyday size, you probably want our standard Ivory Silk Pillowcase (50 × 75cm) instead — same warm ivory, same silk, just the smaller cut. Not sure which your pillows are? Measure one: if it's around 75cm long, go standard; if it's nearer 90cm, this is your size.

The same silk, in a bigger cut
Nothing changes but the dimensions. It's the same 22 Momme, grade 6A long strand Mulberry silk as our standard pillowcase — smooth enough to reduce the friction that causes frizz and sleep creases, breathable enough to sleep cool, and OEKO-TEX certified.
