Surprising fiance long distance?

I’m 16w1d and I’m planning on getting a private scan next week so check for the gender.

My partner and I are long distance (like miles and miles and miiiiiiles away). I would like to surprise him when I find out the gender but I don’t know how. 🤔

I don’t want to do something easy as just saying it outright and sending a box of blue or pink things will be costly and not really worth it. 🤷🏻‍♀️

Most long distance gender reveal articles I see are meant for your parents, friends or others that kind of include ur partner in the planning.

Any ideas?
