Blissy is a real silk pillowcase: 22 momme, Grade 6A, 100% mulberry silk, with a hidden zipper and a published OEKO-TEX certificate number. Whether it's worth it depends on the price you pay. Its queen lists at $105.95, and Blissy's own blog says it's frequently discounted from that price.
I'm Erin Wise, founder of Wink Silk. I sell a pillowcase that costs more than Blissy, and I have no relationship with them. Everything I say about Blissy here comes from its own website, checked on October 30, 2026. Pages change, so check their product page before you decide.
What do you get with a Blissy pillowcase?
Here's what Blissy states, in its own words where it matters.
- Silk: "6A, 22-Momme 100% Mulberry Silk."
- Certificate: OEKO-TEX Standard 100, certificate number 23.HCN.63145. You can enter it yourself at OEKO-TEX Label Check.
- Closure: a hidden zipper on its main pillowcase, per Blissy's own blog.
- Price: $105.95 list for a queen on its pillowcases page.
- Returns: a full refund within 60 nights of receiving it, per Blissy.
That's a legitimate spec sheet. It's real mulberry silk with a number you can check, which is more than many pillowcases in this category give you.
Is 22 momme silk good enough?
Yes. 22 momme is a common premium weight, and Slip and Quince list it too. Momme is the weight of the silk. Heavier silk, like 25 momme, carries about 14% more silk per square meter, so there's more fiber to wear through, and it tends to hold its smooth surface longer through washing. How long any pillowcase lasts depends on how you care for it. Here's what changes between 22 and 25 momme.
What about Blissy's clinical studies?
Blissy says it has commissioned 11 independent clinical studies. Commissioned means Blissy chose to fund them. That doesn't make them wrong. It means you should read them the way you'd read any company's study about its own product. (Mine included, if we ever run one.)
Here's the claim I'll stand behind for any real silk, Blissy's or ours: silk reduces friction against your hair and skin compared with cotton. That's the whole claim. If you have a skin or hair condition, talk to your dermatologist.
Is a more expensive silk pillowcase worth it?
My husband Cooper's favorite superhero T-shirt has been washed until it's see-through. I've tried to throw it out several times. For years my rule has been to buy fewer, higher-quality things, instead of cheap T-shirts that look dingy after a few washes.
But a higher price isn't proof of anything. The specs are. So here's Blissy next to ours, spread over the same two years. That's for comparison only, not a promise of how long either lasts.

Read it honestly. Blissy costs less and gives you a longer return window. Wink gives you heavier silk and a second public certificate. Which of those matters is your call.
How does Wink Silk differ from Blissy?
Wink makes Performance Luxury Silk™: 25 momme, Grade 6A, 100% mulberry silk charmeuse, crafted by a GOTS & OEKO-TEX certified silk house. Wink Silk itself is pursuing its own GOTS and OEKO-TEX certifications. We don't hold them yet.
We don't run sales, so the price you see is the price. The Douceur Doublure™ founding edition is 330 hand-numbered pieces in Coy™, and it will never be restocked. For Blissy next to Slip, see Blissy vs Slip vs Wink Silk. For Blissy next to Quince, see Blissy vs Quince.
