- Complete Blackout: Tired of Light Pollution Disrupting Your Sleep? Our magnetic blackout window film made from premium 420D Oxford fabric (Polyester) that is resistant to wear and tear, achieves complete darkness with our blackout curtains for better sleep, home theaters, or any other use where total light blocking is required.
- Magnetic Installation: Easy to install with no-trace adhesive-backed magnets, allowing for quick and tool-less setup. Simply attach the magnets to your window frame and align the curtain's iron pieces. Once you no longer need black out, the no-trace adhesive-backed magnets ensure that there is no annoying marks on your window frame.
- Thermal Insulation: Maintain your indoor temperature by reducing direct sunlight. Our room darkening window film blocks out all external light, significantly lowering room temperature by preventing sunlight from entering your space, keeping it cooler in summer, and helping reduce cooling costs in a busy city.
- DIY Customization: Easily cut or fold the blackout blinds to fit any window shape or size, providing a perfect custom fit for your needs. Ideal for bedrooms, nurseries, offices, home theaters, and any other space where you need to block out light and maintain privacy.The color of the product are black-silver instead of black-white.
- Our blackout window cover is primarily made from polyester, capable of blocking 100% of UV rays. However, the thickness is less than traditional curtains and may have fold creases which may result in a slight decrease in interior aesthetics. If you are concerned about aesthetics while needing blackout effects, it is recommended to use our product in conjunction with traditional curtains.

First product I have found that isn't lying about it's ability to BLOCK light. You can see this test fit worked great with just the corners secured - the lower left is only letting light through bevause it's gaping, unlike the right where it's closer to the wall. It isn't the prettiest thing but it works, and I could easily sew a fabric on top or put a cute curtain over top. I was also able to use ONE product to cover TWO ftx3ft windows (which even spending $50, most curtains do not cover) but cutting this in half right down the middle. The included razor worked great, and while I prefer magnets it also came with velcro if that is preferable. Very easy to set up and worth every penny, despite being lighter and thinner than the 6 other curtains I have tried. Thank you for finally allowing me to sleep comfortably again

These are so easy to cut to the right size! I was able to cut shades for each window in our camper. The shades are thin which makes for easy storage in the camper when not in use. The magnets are strong and hold well. So far I’m impressed with the quality and think this will last for years. I did not use the Velcro only the magnets for hanging the shades up. I did label each panel so I know exact window to place them on. It made the camper so dark we all slept in later than usual when camping!

Bought these for my three tiny basement windows so my movie nights could finally stop feeling like a matinee at noon. Setup was stupid easy—if you can stick a magnet to a fridge, you’re overqualified for this job. The light-blocking is legit too… like “is it midnight or 3pm?” legit. The material is thick enough to do the job but not so bulky that you’re fighting it every time. Honestly, for the price, it’s a steal. My only complaint? Now I have zero excuses for falling asleep during movies. Highly recommend.

I am pleasantly surprised. I needed back out shades because the sun is beating down into the bedroom. Pros: - It’s light. It feels like a table cloth and it comes out wrinkled like one. It gives instructions how to get them out but I don’t have an iron. - It was simple and easy to cut to fit the window. - it really does block out the light! Cons: - The magnets are heavy and often fall off. They come with extra adhesion sticks but even those have fallen off. - It looks like a cheap plastic table cloth. It’s not pretty at all. Overall I am impressed by how it blocks out the light but I may keep looking since the magnets keep falling off and pulling the shade off the window.

This works!! The moment I put in on, it blocks out all the light. I was so shocked. And very easy to put it on even just by yourself. It is also very big so it can cover a lot of space on the window. It came with a lot of little tools to cut and to put it on. Would 100% recommend!!

Great durability. It darkens the room completely so im able to get a lot more sleep. Surprisingly easy to set up, clear instructions. At first I was skeptical of the quality of the adhesive but it’s holding up very well

It does what it said it does for sure. Blocks out light, comes with magnets and adhesives so you can install it on your window. But it does have a very strong fishy smell. Perhaps the neighbor factory that produces these curtains has fish factory and the smell lingers on it. After washing it with soap and water the smell is gone. My curtain had a few tiny pinpoint holes in it which you can see in a total dark room where light comes through a bit. But its not a big deal as the rest of the curtain block out 100% of the light.
