The sticker is meticulously crafted, the material appears to be of high quality.
The adhesive on the wall, door, etc. is really quite simple and will not take long.
To help, I have previously simply glued a straight line with a spirit level and masking tape and adapted to hand this the sticker.
Visually a real eye-catcher and looks very clean and of high quality.
A Klasser items of decoration.
My absolute buy recommendation. 5 Stars.
