You can learn a lot about copywriting (and marketing!) by paying attention to what’s around you.
Have a look at this sign I saw outside of my local library. “Welcome back to your library.” Not the library, your library. By implying ownership, they’re creating a personal connection. Why is this important? Because we’re more likely to appreciate and care for things we think belong to us.
And this AirPods case…
It could say something as simple as “Made in China”—which would also be true—but it doesn’t. They want you to know it’s Designed by Apple in California. Because all of those words mean something—they represent the luxury and status we associate with the brand. They’re also aware that “Made in China” might have a negative connotation to their customers, so they’ve used the word Assembled.
Each word is deliberate. A cue that reinforces their brand—what you think and feel when you see an Apple product, buy your own, or see their logo.
