Beautifully protect corner

Landsimulated on nonarark in one hotel - the way is relatively simple and beautifully protect the wallpaper at the corner in the passage place. I myself got myself with this problem, because plastic corners did not tolerate, but knock on the corner at the entrance (I have the most painful zone - an entrance hall) or dirty hands grab - the most cute business.

Throwing the idea here, maybe someone will come in handy. An important point - the tree is painted absolutely to the door, so it looks completely natural, as if it was always here.
