For anyone considering these Orange Shields, I would encourage you to ask the company what their guarantee policy is or how they can back up the claim that they prevent tarnish when we have tons of posts from people who have had issues from leaving their hardware covered. It's a fairly new product that seems to have cropped up on IG (or perhaps is made by a member looking to cash in on cautious behavior?) They don't exactly provide a ton of information online and they're rather overpriced for tiny pieces of die cut plastic. I would ask for more information before sticking anything on my 10K bags and I'm one of the less careful members here 
Screen protectors exist to protect the different types of glass on phones but I believe Apple does not encourage use of protectors on their screens due to damage to the oleophobic treatment their screens receive during manufacturing. Pretty sure Hermes wouldn't encourage anyone to apply an aftermarket sticker to their hardware and you run the risk of them declining future service if something did get tarnished under the "shield" that you put on. Just something to think about...
