The window alert sticker reduces the risk of birds flying into your glass doors and windows.
In a choice of Butterfly, or decorative leaf, designs the window alert decal will stick to your window by natural static attraction, so it will not leave marks and is easily removed or replaced. There are four decals per pack.
The window alert will stick to either inside or outside windows and will be effective for two years. It is a good idea to write the date on one of the decals so you will know when to change them.
The window alert reflects the ultra violet light that we are unable to see, creating a brightly glowing warning that is clearly visible to birds.
The sizes are difficult to state as the shapes are irregular, but the Maple Leave is 110mm wide and 120mm long (tip to tip) the Butterfly design is 110mm wide and 110mm long (but is probably more dense than the leaf so the square area of each is very similar to the other.)
Please note - as the Window alert is sent through the post, this item can be delivered anywhere in the UK for free and so is exempt from the zone 2 and 3 charges.
