Listings show three main closure types: zipper closures, side or inner envelope closures, and some with no closure. Zippers and envelope-style closures are the most common options for keeping the pillow tucked in place.
Most listings offer either a single pillowcase or a two‑pack. Product pages commonly list the package quantity as 'Package Quantity: 1' or 'Package Quantity: 2'.
Common anti-slip features include hidden or zipper closures, envelope-style closures, and stay‑put pocket flaps. These elements help keep the pillow tucked and reduce shifting during sleep.
The listings use a range of materials: polyester satin, 100% silk, microfiber, and rayon made from bamboo.
Silk listings emphasize pure mulberry silk, low absorbency (which keeps skin and hair products on the surface), hypoallergenic qualities, temperature regulation, and a cool, breathable sleep surface. Polyester satin listings emphasize easier care (machine wash/tumble dry), color vibrancy, stain- and fade-resistance, wrinkle resistance, and also note hair- and skin-protection benefits.
