Here’s your cheat sheet. Carry-on: disposables, cartridges (attached), and electric. Checked bag: straight razors, loose blades, and safety razor blades.
When in doubt, just buy a cheap disposable at the pharmacy near your hotel. They’re like two bucks, and they work fine. Your travel self will thank you.
Now go pack without anxiety. And if you forget, just lean into the rugged look. Stubble is so in this season. You’re welcome.
