Frequently Asked Questions (FAQ)

What's the Copper Case made of?

We use the best materials possible to optimize the performance of our case. There are four layers: (1) a seismic geometric inner plate for shock absorption, (2) a cushioned TPU liner to hold your phone in place, (3) a tough polycarbonate outer shell, and (4) our proprietary copper nanocoating. Plus, the buttons are coated!


How protective is it?

Our case is designed to withstand the worst of everyday wear and tear, and it has the results to back it up. Don't believe us? We tried to break it, then ran over it with a car. It survived.

Does this case interfere with phone signal, contactless pay, and wireless charging?

Our design does not interfere with phone signal or contactless pay, and our case works with most wireless chargers.

Does copper make the case heavy?

Nope! The average weight of our cases is 50.5 grams — less than competitors. Our durable copper composite nanolayer is thick enough to be functional and durable, while thin enough to keep your phone light and sleek.

Does it deteriorate over time?

While pure copper does oxidize and tarnish over time, our composite technology is resistant to these effects. It will patina, or slightly darken, over time.  However, unlike traditional “Statue of Liberty” oxidation, this patina is not green and will not stain your hands or clothes. You do not need to keep it polished to keep it working, but we do support keeping it in good shape. Clean it often using a soft cloth — see "How do I care for my patina?" below for more.

How do I care for my patina?

Our copper alloy was designed to minimize “Statue of Liberty” oxidation. This means that your phone won’t turn green anytime soon. However, like fine leather, it will naturally patina over time. This means that your copper case will gradually darken, particularly on the areas you touch most. 

At Aeris, we tend to leave our patinas to develop naturally and give a unique look to the case, like fine leather. If you would like to reverse the patina, here is a simple tutorial on how to return your case to its original state. There are many industrial materials that can also help, but we prefer to use common household products.
