BKSAI Magnetic Blackout Blinds (145x200cm) – traceless, removable blackout curtains for bedrooms, no drilling

The essentials

If you rent, share a home, or you just don’t want to start drilling into frames, these BKSAI magnetic blackout blinds are built around a very simple promise: blackout coverage without tools, and removal without leaving residue. On paper, the appeal is obvious—fit them in a couple of minutes, sleep in a darker room, then take them down again in the morning.

They’re designed to stick using a magnetic fastening system (the listing mentions 16 magnets) so you’re not relying on adhesives or screws. The fabric is described as blackout material made from Oxford 420D, which also has a water-repellent finish, so it’s positioned as something you can use day-to-day rather than treating it like a fragile temporary solution.

Key takeaways

What stands out most is the flexibility of the approach: you measure your window, extend the blind material, cut it to size without fraying, and attach it with the magnets. That “cut-to-fit” idea matters if your window isn’t a simple rectangle—especially if you’re dealing with roof windows, slanted windows, triangular shapes, or glass doors.

There’s also a thermal and comfort angle. The listing claims the blackout fabric blocks out light and helps keep the room cooler by reflecting heat from the side exposed to sunlight (via a silver coating). It’s not the same thing as a full replacement blind system, but if your main goal is a darker bedroom and less summer heat through the glass, it’s a sensible direction.

That said, it’s worth keeping expectations realistic: magnetic installation depends on how the magnets sit against your specific window frame and how smooth/consistent the contact area is. If your frame is irregular or you’re trying to cover a very awkward surface, the coverage may feel more “install-and-adjust” than “set and forget”.

What you’ll notice day to day

A practical way to picture using this: imagine it’s late evening and the bedroom still feels bright from outside light. You measure the window area, cut the blackout fabric to your shape, then place the magnets around the frame and smooth the fabric into place. Once it’s mounted, the goal is that you’re no longer getting light leaking around the window edges.

The listing explicitly says it can darken the room to 100% and leave no gaps around the window. In real homes, results can vary a little depending on frame geometry and how precisely you cut and position the material—but as a concept, it’s exactly what you want from blackout curtains.

Where it shines (and where it may fall short)

Where it shines - Renters and landlords-friendly installs: the removable, traceless approach is positioned as ideal when you can’t modify anything. - Unusual window shapes: the cut-and-fit method is aimed at anything from slanted or roof windows to triangular and angled openings. - Everyday blackout needs: it’s marketed as blackout blinds for bedrooms, with a water-repellent Oxford 420D fabric for durability.

Where it may not suit - If you need a more “built-in” finish, you might find magnetic setups less tidy than a permanently fitted solution. - It can be overkill if you only want light filtering, not full blackout coverage. - If your window frame doesn’t give a stable magnet contact surface, you may spend more time adjusting placement than expected.

Quick sizing and installation notes

Before you buy, double-check whether 145x200cm is enough for your window area once you account for the shape you’re covering. The listing says it’s “any shape and size” in the sense that you can cut the fabric without fraying, but you’ll still need the base size to physically reach your measurements.

Also, while installation is described as tool-free, take a moment to think about where the magnets will sit on your frame. The “no gaps” claim relies on good contact around the perimeter, so measuring carefully and smoothing the fabric into position matters.

Is it worth it?

This is a strong pick if you want proper blackout for a bedroom and you specifically need a no-drilling, removable solution—particularly if you rent, want flexibility, or have a roof window, slanted window, or other tricky shape where traditional blinds can be a faff.

You may want to skip it if you’re looking for a permanent, perfectly tailored finish, or if your window frame doesn’t offer a reliable surface for the magnets to hold evenly. In those cases, the magnetic approach can feel more “work required” than you hoped.
