Mr. Shield Japan Tempered Glass
A popular trend lately is full-cover screen protectors that are color-matched to perfectly fit your device.
The Mr. Shield Tempered Glass 2 pack is a great example. This is your typical tempered and reinforced glass, but the glass is black to match the phone. All except the 5.5-inch cutout for the screen. They use extra strong Japanese glass with a 9H hardness rating, perfect clarity, and beveled edges so it won't chip or break over time.
If you don't like the way a screen protector looks or feels on the edges, consider this option. You'll get two, just in case one goes wrong.
