I am really happy with quality of the glitter stickers.  I have been ordering from sticker mule for over 4 years.  I have never had issues.  If you keep in direct direct sunlight (like on a car out in elements). The stickers do fade.  But nothing else on market will be fade free if you keep it in sun.  Stick on water bottle or laptop. Those have lasted perfectly for several years. One thing that sticker mule stands out for is ease and speed.  Plus the color/coloring/design print pops.  I have used a few other sticker places as well, and am always most happy with sticker mule.
