I've always put a skin on my mobile devices while they are shiny and new. They keep off scratches and minor dings and are thin enough not to interfere with putting it in a case. And they also stop the device from feeling slippery.
Amazon already has a couple of these with full body coverage made from military grade clear plastic. [Kindle Oasis Anti-Glare Screen Protector [Full Coverage], IQ ShieldŽ Matte - Full Body Skin with Lifetime Warranty Replacements - Premium Bubble-Free HD Film with Anti-Fingerprint Coating].
Decal Girl [
