This Duvet Cover is made of Sandwashed Mulberry Habotai silk.
The colour is Ivory. This is actually Mulberry silk's natural colour: That means there is no dye that might fade or run in the wash.
It has piping on the side and bottom edges. It has a zippered opening.
The zip is scarcely visible and it's so much easier than buttons.
Washing hint:
The sheets can be washed at 30ºC. Use a washing soap recommended for silk and wool. Spin gently and hang-dry. They then scarcely need ironing. The sheets can be dry cleaned, but 30ºC washing is preferred
