The phone is new. They have no habit yet. A slim adult case looks good in the box and fails in a backpack. Start with a drop-proof bumper and a design they will actually leave on.
Confirm the exact model in Settings → About — not the box. iPhone 16 and 16 Pro are different. Then pick space, hero, or a cleaner unicorn/dino print if they still want one.
$24.99, free shipping, 30-day returns. Add a screen protector the same day.
Most first-phone orders here are ages 10–14. A 15–17 year old may want a simpler look — space and hero are the usual picks.
Schools usually ban using the phone in class, not putting a case on it. This is a regular protective case.
Borrow the phone for thirty seconds and open Settings → About. Do not guess from the box they threw away.
