Blackout Blinds Stick On 300x145cm – 100% Blackout, 420D Fabric, Cut-to-Size & Portable

What this is and what it solves

These blackout blinds are a stick-on, temporary solution designed to block out light from windows using a thick 420D fabric. They’re sold in a 300x145cm size and can be cut to fit a variety of window shapes, from standard rectangles to bays or skylights. The aim is simple: to create a darker room for better daytime sleep or a more restful environment when ambient light is a concern, without the need for drilling or installing hardware.

How it works in practice

The product is lightweight and portable, supplied with 18 round adhesives and 12 loop tapes, plus a storage bag. The setup is described as a straightforward three-step process: measure, cut, stick. After use, you can remove it without leaving holes in the wall, and the adhesive remains on the shade for future applications. In terms of care, the description mentions it can be folded away and machine washable, though it also notes dusting with a damp cloth as a cleaning method. If you’re on the move, the included storage bag makes it easy to carry and store.

What’s good about it

• 100% blackout material stops light and UV rays on the window, which can help improve sleep quality in daytime and create a darker room for activities or rest.
• Cut-to-fit design makes it versatile for different window shapes and sizes without bespoke manufacturing.
• Lightweight and portable, suitable for home, office, or travel use, the storage bag aids in keeping everything together when you’re on the go.
• Simple installation with no drilling or tools required, particularly appealing if you rent or want a temporary solution.

Areas to consider

• The fit depends on accurate measuring and cutting, there’s a small tolerance in edge clearance (2–3 cm) to prevent light seepage. If a window has unusual angles or protrusions, this method may require careful trimming.
• Care guidance in the listing is a bit mixed (machine washable vs. dust with a damp cloth). If you’re hoping for a low-maintenance option, you’ll want to follow the care recommendations that best fit your routine.
• While the product is marketed as portable, the sheer size (3 m long) may be less convenient in very small spaces unless you have a method to store it flat or wrapped.

Who it’s best for

• Anyone seeking a temporary, non-permanent blackout solution for bedrooms during the day, hotel stays, or hotel-like guest rooms.
• People renting a space who cannot or prefer not to install permanent window coverings.
• Travellers or home workers who want a portable light-control option for day-to-day use.

Who might want to think twice

• If you require a perfectly sealed, permanent blackout curtain, a fixed or ceiling-mounted solution could be more durable in the long run.
• If your windows have irregular shapes or very tight recesses, achieving a completely light-free edge may be more challenging and require careful trimming.

When it makes sense to buy

• When you need a quick, non-destructive blackout solution that can be cut to fit your window and carried in a bag for travel.
• When you want the option to remove without leaving marks or requiring tools, for short-term stays or rental properties.

What to check before purchasing

• Measure the window area accurately and plan for a 2–3 cm extra on the edge to reduce light leakage.
• Consider where you’ll store the shade when not in use and whether the size fits your storage space.
• Review the care guidance to align with your cleaning routine, the product mentions both machine washing and dusting with a damp cloth.

Practical use example

Imagine a day-sleeping child or a person needing a dark environment to nap during a bright afternoon. You can measure the window, trim the shade to fit, and stick it on with the included adhesive pieces. When the nap is over, you roll the shade up, store it in the bag, and it’s ready for the next trip or return to a sunlit room.

FAQ (based on available information)

• Is it reusable? Yes, the system is designed for multiple uses with re-stickable adhesive and tapes.
• Can it be used on car windows? The description mentions various window shapes including car windows, suggesting suitability, though results may vary by vehicle spec.
• How do you clean it? Dust it with a damp cloth, one line also mentions machine washing, but care guidance may differ.

Is it worth it?

Worth considering if you prioritise a flexible, non-permanent blackout solution that travels well and doesn’t require mounting hardware. It may not be the best option if you need a flawlessly sealed edge every time or if your window shape is highly irregular.
