SHADING ROLL SCREEN DOLPHIN WH 80X220

Attaching it to the curtain rail is really easy. Removing it is also easy, just press the protruding part. However, you shouldn't expect it to completely block out light. You can't see any shadows from outside at all.

I was looking for a blackout roller curtain, and this was the product that met my requirements in terms of price, size, and installation method. It's easy to install, but depending on the position of the wall where you install it, it might be better to use special screws (like the kind that expand inside the wall).
