Totu makes many covers here is one of them and they are as always super delicious, they are made of the best material, it is made of silicone so it is soft and takes shocks and is really good at preventing scratches. 

Silicone, specifically Thermoplastic polyurethane, which is good for covers because it is soft and therefore is good for absorbing shocks and distributing the shock out in as large a area as possible, is elastic so it is easy to get on your iPhone even though it sits very close , oil and grease are resistant so it doesn't get disgusting. 

Thermoplastic polyurethane is also good because it can be made very thin so you can enjoy too small your iPhone's and especially how thin it is. 

The cover here is made for the iPhone Xs Max, it's made to fit just the iPhone so it sits perfectly on it. 

The cover has buttons on it so you don't have to press harder than usual to press the buttons because they're hidden behind a cover. It's only the silent button that doesn't have a button, so it's hidden away a little bit and therefore doesn't get hit by accident.

You can get the cover in black or white, the white is transparent and the black is also transparent but has a matte black color. Both then let the color of your iPhone through.

Then you need a cover that protects really well, lasts long and doesn't fill anything it's this cover you need.
