Slip Silk Pillowcase
The verdict
100% pure 22-momme mulberry silk with a hidden zipper closure, machine washable on delicate. Slip sells ONE Standard/Queen size — 20 by 30 inches — not separate Standard and Queen sizes; King is separate at 20 by 36.
Slip Silk Pillowcase — about $89–$120 (price varies by seller and color) · ≈4.5/5 from ~1,700 Amazon reviews (4.8/5 from ~1,778 on Ulta) · the 22-momme silk pillowcase — and the one where the size name is the trap.
The page names the size explicitly so shoppers do not hunt for a Queen-only variant that does not exist.
Specs
- 100% pure 22-momme mulberry silk

- Machine wash delicate; pH-neutral detergent
- One pillowcase, not a pair
Blind details
For a blind shopper, the buy decision is the momme count: 22-momme mulberry silk is the spec to verify in the title, because cheaper 'satin' pillowcases are polyester, not silk. The hidden zipper is the practical detail — no envelope flap to fight with — and the wash-care commitment (pH-neutral detergent, no bleach, no tumble dry) is worth reading before buying, not after.
Honest caveats: premium price for ONE pillowcase, not a pair; anti-aging claims are brand and lab claims, not guarantees; light colors stain more easily with skincare oils. The Amazon price was not cleanly isolated in our research — Ulta $120 (Queen), Nordstrom Rack $74.97 on sale — so confirm at checkout. As of October 2026 the range was $89–$120.
