A letter they open at exactly the right moment.
Write something sealed. It unlocks when they land, when they arrive home, or at the second hand you choose. Tuck in a photo and a small gift for the road.

Questions
Good things to ask.
- What is an open-when letter?
- A note someone opens only at a chosen moment — like when they're missing you or when they land somewhere. Stowaway makes it unlock automatically at the time or place you set.
- How does the letter unlock?
- You pick a time, or a place. The letter stays sealed until then; the content isn't shown until your moment arrives.
- Can I stay anonymous?
- Yes — you can hide your name until the moment they open it.
