satin or silk pillowcase

Most listings specify 100% silk, commonly described as mulberry silk or 'pure'/'real' silk.

Common standard sizes shown are queen (20" x 30") and king (20" x 36").

Listings use either a hidden zipper/zip closure or an inner envelope-style closure (often a 6" inner envelope).

Care instructions vary by listing, but most note machine washability; drying recommendations differ—some allow tumble drying while others advise line-dry or lay flat to dry. Check the product tag or listing for the exact guidance.

Listings often use 'satin' to describe the finish or surface feel while specifying the material as 100% silk—effectively pairing a satin-like surface with pure silk fabric.
