For long-distance couples: what gift actually felt meaningful (not just cute)?

I’m trying to put together a thoughtful gift for a long-distance partner and want ideas that actually have emotional impact.

Budget is around $30–80, and I’d rather avoid generic stuff that gets used once and forgotten.

If you’ve received or given something that genuinely meant a lot, what was it and why did it work?

(Especially interested in ideas that can include shared memories/photos, but open to anything practical too.)
