pa·ti·na — the natural aging process that occurs on the surface of leather products over time. As leather is exposed to 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 policy with the link at the bottom of the 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.

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.

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!

Great

"Excellent case, I’ve gone through Nomad, Ryan London and Andar, all of which are great vases but my favorite is the bullstrap. Feels genuinely tough and rugged whilst having few creases and wrinkles in the corners. One of the few to make a 17pro case without exposing the whole plateau too!"

— Alexandre C. (5/5)

Recommended purchase for leather aficionados

"Leather is best quality, smells great and will patina with time . Expensive and pricey yes, but for an investment of a quality leather, this is justified and will get beautiful over time . Button also is clicky , and quality is sensational. Leather now covers at the bottom, which is 1000% more Better than Apple leather phone case prior ."

— Syazwan Z. (5/5)

More Than Just a Phone Case

Q&A

In theory this is exactly what I want. Just need to carry two cards and probably will never stack multiple cards into one slot. I am concerned about a card falling out. How secure are they?
They’re very secure! Just keep in mind to store only up to 2 cards per slot. Over time, the slots can naturally loosen a bit, but if that ever happens, you can easily file a warranty claim with us.
Is there a case that fits the iPhone 16e model?

How long can I expect to wait for the iPhone 13 pro portfolio case in sienna, it is currently back ordered?
Hey Danielle, They should ship out on or after 3/31!
Just opened my new case and it only has one of the credit card slots? Is there a reason it’s missing the second?
Hey Keri, All of our iPhone Portfolio cases have two slots except the iPhone 12 mini and 13 mini Portfolio cases which only have 1 slot.
I would like to spray my new case with leather protector. Any problem with that.
