I think I’m gonna go old school w a wax seal on it and

I want some kind of paper that would complement that. Also does anyone know if the type of ink you use could effect how long it lasts? He may keep it as a keep sale for a long time. Ie years. And where would I find an envelope that complements the paper I print it on? Any other tips for love letters appreciated. I already know what I’m writting in it though. I just want a nice presentation for it. it would also be his 10

Th anniversary gift. So I want it to look nice and last.
