Bird Protection Stickers – Pack of 5 I Window Film for Bird Repellent I Black | Stickers for Windows, Doors, Conservatories I Window Protection Against Bird Strikes | Window Pictures

Easy to stick on the window, and they seem to stick on well. Two of them were smaller than described - one was 16cm and one only 12 cm on their longest side. I am waiting to see if they do the trick and deter birds from flying into the window.

Ordered 1 got sent 2 presumably paid for both.But no more birds flying into the window so the work, best i can say.

Prevents my feathered friends from colliding with the window, thereby saving them a headache.

Very tasteful and look good on the window. Hopefully will deter the young birds from flying into them

Putting on glass around our decking to stop birds flying into it. Also for the same reason on our front window which is near bird feeders

Stuck well, look attractive and have kept birds away from the window.

These were easy to apply and certainly do the trick

Item was great but they don’t stop birds tapping on your window
