We all hate mean people and this Be Nice or Leave Decal is a good answer to those who stop by your doorstep time and again. They are a super awesome reminder for your guests to behave well and be less mean when they step at your place. The cutout areas of the design will allow your door color or wall color to show and adds a natural feel to the entire look of the decal that way. You can get it in a range of matte colors which have been especially handmade in Helsinki. Time to look smart in terms of decorating your indoors with quotations that let you speak your heart.
