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.

How many cards fit in the portfolio case?

Our Portfolio iPhone cases allow for 1-2 cards per slot, adding more than the recommended amount will stretch the stitching and potentially damage the case.

Are your cases compatible with wireless charging?

All of our iPhone cases are compatible with QI (standard) wireless chargers.

How much protection do these cases offer for dropped phones?

Our production and research team has conducted a series of drop tests across the different sizes of phone cases that we offer. After conducting these tests, we’ve concluded that anything within a six foot drop is where we know the phone/case remains safe. We’ve obviously had tests where both the phone and case consistently survive harsher throws and drops, but within six feet is an extremely safe range.

Are Bullstrap products waterproof?

While our high-quality genuine leather Bullstrap products are splash/water resistant, we do not recommend submerging it in water as it will cause the leather to darken considerably and become more firm. We recommend using our Leather Care Wipes for keeping your leather accessories in it's best shape!
