black silk pillowcase

Most listings use zipper closures—commonly described as hidden or concealed zippers—to provide a secure, fully enclosed fit.

Several listings describe silk as naturally temperature-regulating, noting it feels cool in summer yet comfortable and cozy in cooler weather.

Available sizes include Standard (20" x 26"), Queen (20" x 30"), and King (20" x 36"). The results also show smaller square sizes (for example 15.75" x 15.75") and other measured dimensions up to 36" x 20".

Most listings specify silk—several list 100% silk—while some items are satin-style covers made from 100% polyester.

The listings show momme values of 19, 22, and 25. For thread count, a 450 value appears in some details, while other entries list thread count as “Not Applicable.”

Care instructions vary: several listings recommend machine wash on a delicate cycle (with some allowing tumble dry), while others advise hand wash and hang or line dry. A number of entries explicitly state not to tumble dry.

The results include both single-pillowcase packages and 2‑pack sets.

Listings highlight double-sided silk for durability and use hidden or concealed zippers—sometimes reinforced—to keep the pillow fully enclosed for a seamless, secure fit.
