Complete Blackout: Tired of Light Pollution Disrupting Your Sleep? Our magnetic blackout window film made from premium 420D Oxford fabric 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.
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.

No more light
I have blackout curtains— but they still let in light. I sewed blackout curtain liners, into my curtains, blocking most of the light. Unfortunately, light came in through the sides and in the middle of the curtains. I can’t sleep with light. My bedroom is next to a bright street light which shines into my back bedroom. I live in Texas, so my bedroom gets a lot of light.These window covers are amazing! There is no more light. My bedroom is pitch black; which is perfect. The covers are very lightweight and easy to use or reuse.I didn’t use the magnets instead I used pushpins from my home office. The size fit my windows perfectly. It wasn’t excellent value and exactly what I needed. I’m very happy with this purchase.

Reliable and functional window blackout covers.
Comes with everything you need to get it set up. Read the instructions to make sure once you put it up, it sticks indefinitely. I had no issues. Carefully measuring your window, and the piece you cut out for that window. will make a difference in how much light is filtered out. It is true that it is 100 percent blackout, but you must make sure you cover the window entirely with the material so little cracks of light don’t seep in around the seems. Unless that doesn’t matter to you. I found this very useful in my camper. I was able to cover two regular camper windows and 1 small camper bathroom window with material to spare. I noticed in the summer it will block out a lot of heat. Make sure the silver side faces the outside part of the window for it to reflect heat. I’ve even noticed it has blocked some of the cold from coming in the windows of the camper during the colder months too. All in all they have held up really well so far without losing any stickiness. I highly recommend.

A great surprise!
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.

Super useful
Got these cause i have existing blinds in my apartment. This thing is super useful. Blocks out light very well and very convenient to remove and put back up. I’m not having any issues with the adhesive it seems super strong and isn’t showing signs of not sticking. However, the ashesive is stuck to the metal window frame, not the wall, this could have impact on stickiness.

easy, lightweight, and worry free
Lightweight and very effective! The directions on these made no sense at all; so just forget those. But once I figured it out, VERY easy to install and made a huge difference. It is nice to be able to put something on my window without it begin bulky or difficult. I will not be worried about this falling do or anything.

Technically it blocks light, but the images in the store page were misleading
It does the job for blocking light. That said, the product I received is thin and likely not durable.The thickness isn’t an issue in itself, but is advertised with image that appears to show a somewhat complex and robust multi layer design with the different layers providing different features. The product I received is a single layer of synthetic fabric That doesn’t look and feel so much different from a disposable table cloth. But despite it being thin, it does block out all light when installed flush with the window frame.Edit: I changed to 3 stars since the seller was willing to repay me.

BKSAI Cuttable Blackout Window Covers
Impressive Blackout Solution – Almost PerfectI’ve been using the BKSAI Cuttable Blackout Window Covers for a few weeks now, and overall, I’m really pleased with how well they perform. I was searching for a flexible, non-permanent blackout solution for my bedroom and office, and this product mostly delivers on what it promises.One of the standout features is that the material is cuttable, which made it easy to customize the covers to fit my unique window sizes. I appreciated how straightforward the process was—just measure, cut, and stick. The blackout material is thick and effective. Once installed, it made a noticeable difference in blocking sunlight and even helped with temperature control, which was a pleasant surprise. My room stays cooler during the day, and the light reduction has significantly improved my sleep quality.The design is sleek and minimal, and the black color adds a clean, modern look. These covers are especially great for renters or anyone who doesn’t want to install permanent blackout curtains or shades. They’re easy to remove and don’t leave any marks or residue behind, which is a big plus.The only reason I’m not giving 5 stars is due to the adhesive backing. While it holds well for the most part, I noticed that a couple of corners started peeling after about a week. I had to reinforce them with some additional tape to keep them secure. It’s not a dealbreaker, but it’s something to be aware of if you’re planning on using these long-term or in a room with high humidity or heat exposure.All things considered, the BKSAI Cuttable Blackout Window Covers are a great value and a smart solution for anyone looking for a customizable way to block out light without breaking the bank. With slightly improved adhesive, this would easily be a 5-star product.
