Listings show satin pillowcases made from either 100% silk or 100% polyester satin; some listings simply label the fabric as “satin” without specifying a fiber or thread count.
Common dimensions in these listings include 20" x 26" (Standard), 20" x 30" (Queen), and 20" x 36" (King). Other sizes shown include 30" x 20", 36" x 20", and 26" x 20".
Many listings are sold as a single pillowcase (package quantity = 1), while some are offered as two‑piece sets (package quantity = 2).
Most listings show an inner envelope closure (commonly a 6" envelope, sometimes 8"). Some listings indicate no specific closure (open-ended), which may allow easier insertion but less secure containment.
Care instructions vary by listing: many state machine wash and tumble dry, while others recommend warm or gentle cycles and tumble‑dry‑low. A few mention occasional low‑heat ironing. Because care recommendations differ, follow the specific product listing or the pillowcase’s care label for best results.
Descriptions commonly say satin reduces friction on hair and skin (helping prevent tangles), can reduce hair breakage and frizz, and absorbs less moisture than cotton so skin may retain more hydration and sleep lines may be minimized.
Some polyester satin listings show numeric thread counts (examples include 400 and 700), while other listings — especially those that simply list “satin” — report thread count as “Not Applicable.”
