Brighten up a boring window with some of these fun decals. One of the cool features of a soft flexible like NinjaFlex (SH=85A) is that it sticks really well to windows and mirrors when printed at 1mm to 2mm thickness. It's important that your print surface and the windows you stick the decals on are clean ;) to insure smooth against smooth. Just wet with water and stick. I have some up in my office that have been there for months. Check out my other decal designs under my profile.
