What are "Open when" letters?
"Open when" letters are a set of sealed notes, each labelled for a specific moment — "Open when you miss me", "Open when you're sad", "Open when you can't sleep". Your partner opens each one only when that moment arrives. They're a beloved long-distance relationship gift because they put you there for the hard days, even when you can't be.
