At the delivery: shipping by traders, a day later, on the package. The Mural was in very securely packed.
After unpacking we found a guide, this was very helpful, the steps are shown in pictures, you can see the dimensions and has a description of how to install the wallpaper. We have just described the procedure as shown on the instructions and everything has worked wonderfully and smoothly and even though I'd never have to do with a photo wallpaper.
All parts fit perfectly and without gaps. The wallpaper has not warped, as described by a customer here on Amazon. One should simply proceed according to the instructions, it worked excellently with me and my wife. The wall paper is very high and the quality of the print is very good, the overall picture is colorful (the colors are really great and worth the space on) and has thrilled our little ones immediately. We had no problems and recommend the product. We are very happy, especially my kids, who are completely blown away.
