Instead of buying this $US5 decal and pretending that your super sophisticated 21st century smartphone is an old Nintendo controller, why not pretend that you just happen to have a magical NES controller that can run apps and make phone calls?
Sometimes make phone calls, anyway - It is only an NES controller, after all! The decal, which can be had for $US5 on Etsy, is made for the iPhone 4 and has a little hole for its camera.
All of our stickers are printed using solvent ink on quality vinyl and then passed through one of our giant plotters and die cut. This isn't cheap sticker paper from an office supply store, this is certifiable vinyl powered awesomeness. Rated 5-7 years of outdoor life.
