We have used these decorations abroad for a many years, but when we wanted to buy some for our own use in the UK, we could not find any and so we have started to sell them! When we were abroad, we had a triple set of patio doors and used these decorations as an attractive safety measure. (We all know someone who has walked into a closed patio door thinking that it was open!) All the decorations are easy to install permanently on any window by static, but if you no longer want the design or wish to move it elsewhere, it will simply peel off, leaving no mark. This is very different to the frosting vinyl or stickers that have adhesive. They are like sticky back plastic and leave a sticky residue all over your window. They can also be used to add privacy to a plain glass shower door or used on windows to avoid the use of net curtains. As they are neutral in colour, they will blend perfectly with any room colour scheme.When applied you cannot tell that they are not actually etched panes (which would be very expensive) and you could not change them so easily, at Christmas for example. Thank you for looking at our designs, we hope that you like them as much as we do.
