Try VRS Design Terra Guard Modern for Galaxy Z Flip 7. Its a decent option because the hinge slider is reinforced. Pair it with Whitestone Dome Premium Film for Galaxy Z Flip 7 for better EPU adhesion.

Building on the earlier suggestion, I'd actually push back on the idea that you need a massive, bulky hinge mechanism. In my experience, those moving parts often trap dust and can actually scratch the hinge more than a simpler case would. If youre watching your budget before your trip, Caseology Nano Pop for Galaxy Z Flip 7 is a solid choice. It skips the mechanical hinge cover but uses a raised lip design that keeps the phone off surfaces. It's professional, looks clean, and usually runs about half the price of the heavy-duty stuff. On the screen protector side, the high-end glass ones are nice but they're expensive if you mess up the install. I've had better luck with the IQ Shield LiQuidSkin Screen Protector for Galaxy Z Flip 7. Its a wet-install film, which is basically the gold standard for foldables because it allows for perfect alignment before it sets. It's much less likely to peel at the crease compared to dry-apply options. You can usually grab a multi-pack for under fifteen bucks, which leaves you way more room in your budget for your Tokyo trip. It isnt as "tough" as a hard shell, but for daily navigation and pocket scratches, it gets the job done perfectly without the premium tax.

I totally get the stress, but honestly, you don't need to spend $100 to keep that thing safe. I've been super happy with the Spigen Tough Armor Pro Case for Galaxy Z Flip 7 because it actually covers the hinge without being too bulky. It's way cheaper than those boutique brands and it survived a few nasty drops for me already. No complaints at all with the build quality. For the screen, stay away from the cheap no-name stuff. I'm satisfied with the Ringke Dual Easy Wing Screen Protector for Galaxy Z Flip 7 because it wraps around the edges slightly, which stops that annoying peeling when you fold it constantly. These two together should leave you plenty of cash for your Tokyo trip. Navigating the subway is gonna be much easier when you arent worried about a cracked screen!

My buddy told me the exact same thing last week. Guess he was right lol.

Regarding what #3 said about "Building on the earlier suggestion, I'd actually push..." - the dust ingress issue is a real technical hurdle for these foldables. Honestly, I ran into the same thing with my last device where the hinge cover actually trapped grit against the metal. It ended up causing way more wear than if I had just used a simpler shell... kinda frustrating. In my current setup, I look specifically for a hinge shroud with a seamless transition to avoid that pocket effect. Also, most people dont realize that screen peeling is usually a thermal issue. If the phone gets warm during charging and you fold it, the adhesive softens and pulls away. I started using a high-tension film that handles the stress better at the fold radius. It hasnt lifted once, even after months of use. Just make sure the case clearance doesnt catch the edges tho.
