I finally tried a fancy leather case.

"Case flexes out at the camera button and the sides can be slick at times. The leather is top notch and looks amazing!"

— Dwayne B. (3/5)

"Stellar Quality!"

— Devon (5/5)

"I had a Bullstrap case on my last iPhone and absolutely loved it. It was the only case I had for that phone for two years and it just got better with age. So when I switched iPhones, I was excited to get another Bullstrap case. This one was as beautiful as the last one, however, the little flush button that operates the camera – for whatever reason it is extremely sensitive with this case and every time I pick up my phone, I wind up taking a picture of my foot or a table top or the console of my car. I got so tired of it that I’ve stopped using the case. I have another case that doesn’t do this. It’s not as nice as the Bullstrap but it’s less of a hassle. Yo.Its a shame because the Bullstrap looks so great."

— Rob (3/5)

I really like the flex

"I really like the flex case. With the TPU on the sides I feel better protected for drops than the all leather case."

— Harvey B. (5/5)

Button cutout flaw

"This is the perfect case but the cutout for the bottom right button completely weakens the protection of the phone. That little strip that goes over the button is paper thin and because of that the case can be pushed off the phone easily and reveal the corners of the screen. If I dropped the phone on its face there is no doubt that corner would be exposed and hit very hard because of that cutout and weak banding."

— Ned (3/5)

Great case. Would definitely purchase

"Great case. Would definitely purchase again."

— Andy B. (5/5)

Q&A

What is the best way to remove a Bullstrap flex case from an iPhone 16?I have tried several times and the close fit which I love is making it impossible for me to remove.: Thanks for reaching out! The best way to remove your Bullstrap Flex Case from an iPhone 16 is to gently start from one of the bottom corners, slowly working your way around the edges without using too much force to avoid any damage.
You show the Flex case for the Iphone 15 Pro with the same extra opening on the right side for the camera control button. Is this correct, as this button does not exist on the Iphone 15 Pro.: Thanks for reaching out! No, the Flex Case for the iPhone 15 Pro does not have an extra opening for a camera control button.
