Sleep Under the Stars with Our Contoured 3D Blackout Sleep Mask
Right, so here's the rather brilliant bit: we've designed a sleep mask that actually works. Inspired by those genuinely peaceful nights and dreamy skies that seem to exist mainly in Instagram photos, our Contoured 3D Blackout Sleep Mask in Night Sky print helps you drift off into proper, uninterrupted rest. No matter how aggressively bright that morning sun insists on being.
Why Choose Our Sleep Mask
Total Light Blocking: Our 100 percent blackout design is absolutely ideal for light sleepers, shift workers, and anyone who occasionally fancies a lie-in that doesn't end at 6am. The kind of darkness that actually lets you sleep, rather than that half-hearted dimness other masks offer.
3D Contoured Comfort: The thoughtfully shaped design protects your lashes and gently relieves that awful eye pressure you get from most flat masks. Pressure-free comfort, as it were, without making you look like you've been in a minor scuffle.
Breathable Fabric: Super-soft material that won't leave you sweating like you've just run a marathon. Your face stays cool, your comfort stays high, and everyone's rather happy about it.
Secure Fit: The adjustable hook-and-loop fastening stays put without slipping, whether you're sleeping at home, on a flight, or pretending to be asleep in a meeting.
Soothing Design: The Night Sky print is genuinely lovely. Not that a print can technically improve sleep, but it's certainly more pleasant to look at than the ceiling at 3am.
Product Details
Material: Soft, breathable fabric that feels rather good against your skin
Coverage: 100 percent light blocking for proper, genuine darkness
Fastening: Adjustable hook-and-loop strap for a secure, customisable fit
Design: 3D contoured shape to protect lashes and minimise pressure
Best For: Home sleep, shift work, travel, and anyone who takes their rest seriously
Note on Lash Extensions: We've carefully designed this mask to work with eyelash extensions. That said, lashes do vary rather considerably in length and type, so do use your own judgment to determine if this is the right fit for you.
A rather good investment in the sort of sleep that actually makes you feel human again. The kind of purchase you won't regret at 3am.
SHIPPING + RETURNS
THE RATHER IMPORTANT BITS
This rather lovely piece ships directly from our brand partner - we work with independent brands who are absolutely brilliant and work frightfully hard to create beautiful things.
SHIPPING DESTINATIONS
Now, here's the thing - our wonderful brand partners ship to lots of different places, but not all of them can ship worldwide.
Some are brilliant at international shipping, others prefer to keep things closer to home.
At checkout, you'll see exactly where this particular brand can send your goodies.
We're terribly sorry, but shipping costs do vary rather wildly depending on where you are in the world. The exact figures pop up at checkout - no nasty surprises!
RETURNS
You have 14 days to return items.
Now, we absolutely adore our brand partners - they work incredibly hard and we do try to support them as much as we possibly can. So I'm rather afraid we have to pass the return postage costs back to you. Frightfully sorry about that!
🌍 PLEASE CHOOSE THOUGHTFULLY:
Our wonderful partners put their hearts into everything they make.
Ordering multiple sizes to try at home is rather hard on our planet and makes things jolly difficult for these brilliant independent creators.
When in doubt, do ask us first!
PAYMENT
We're frightfully modern and accept all the usual suspects:
Visa, Mastercard, American Express, PayPal, Apple Pay, Google Pay, and Shop Pay
SECURE AS HOUSES
Everything's properly encrypted and secure - your details are safer than the Crown Jewels!
All prices in lovely British pounds £ GBP, though international chaps will see converted prices.
Any payment pickle? We're here to help sort things out! Contact us
We Have Lots More Like This.........
Hello, we are Sostter....
Sostter began, as all good ideas do, with a lively conversation and a shared sense of frustration. Why had the world of independent design become so serious, so samey, so… beige? Where was the spark, the imagination, the sheer joy of discovering something that made you stop and stare?
We dreamt of a marketplace that celebrated difference — where curious minds could explore a world of independent brands, design-led makers, and thoughtful artisans. A space that felt exciting, human, and beautifully imperfect.
Today, Sostter brings together remarkable people and their creations — from London to Lausanne, Brooklyn to Berlin — uniting makers and discoverers through craftsmanship, creativity, and conscience. Every object tells a story, and every purchase supports an independent brand doing things differently.
This is just the beginning. But enough about us — step inside, explore our world, and see what catches your imagination.
Giving Back
We’re proud to support Sutton Night Watch, a grassroots UK charity making a real difference in the lives of those facing homelessness. Through regular donations of stock, supplies, and essentials, we back their mission to offer warmth, dignity, and practical help to anyone in need — right where it matters most.
