I have assembled this perfect fit white roller blind which measures 40cm width and 75.5cm length (does extend longer). It requires no drilling as it fits perfectly in the window. It was bought for £90+ and is practically new as all I did was put it up in my bathroom and realised white does not match my decor. I took it down immediately. This is why I need to sell it. I have all parts required to put it up and fit securely.
