Personalized Walnut Anniversary Letter Archive

A personalized solid walnut archive for the letters that become part of your story.

The Anniversary Letter Archive is a personalized solid walnut anniversary gift for couples, designed for yearly love letters, milestone anniversaries and especially meaningful as a fifth-anniversary wood gift. It brings together an extra-large walnut keepsake box with ivory writing paper and envelopes for messages written now and opened in the years ahead.

Personalize the sliding lid with an archive title, names and a meaningful year or date, then add an optional private message inside. Use the included paper for anniversary letters, promises, reflections or notes to your future selves, and return to the box each year as your story grows.

The included starter writing set contains 8 acid-free ivory lined sheets and 4 acid-free ivory envelopes, with room to add more letters and meaningful paper keepsakes over time.
