PATINA PROUD

100% FULL-GRAIN LEATHER

pa·ti·na - the natural aging process that occurs on the surface of leather products over time. As leather is exposed to elements such as light, air, and handling, it develops a unique, rich sheen and darkens in color. This change is often considered desirable because it enhances the leather's character and beauty, giving it a distinctive, lived-in appearance.

FAQ
Is this product really covered by a Lifetime Warranty?

Yes, it’s real. And it’s awesome. If you want to read some legal nonsense, you can learn more about our Lifetime Warranty by clicking the link at the bottom of this page. But suffice it to say, we’ve got you covered.
Do the Flex cases have a lock magnet?

Yes! It’s the magnetic line under the circle of magnets to help it stay in place and not spin around.
How does the Flex case differ from the Minimalist case?
The main difference is protection! The shock absorbing TPU rim on the Flex case will protect not only your phone, but also the full-grain leather backing from getting torn on the sides. Other than the sides, the phone case are both MagSafe compatible and made with the highest quality leather on the market.

We added this extra protection to prevent ripping/tearing on the edges of your case! We understand leather and while it may be beautiful, it sometimes doesn't withstand being dropped on concrete. That's why we made this case. for those who want the look of a leather case with also the protective characteristics of a plastic case!
