Sending letters internationally from Lebanon

hi guys

l have an online friend living in europe that I want to start mailing actual letters or postcards to. problem is that i've never done this before and the liban post website is very outdated and doesn't help.

i tried looking at the rates of other carriers but its straight up robbery, aramex has 50$ shipping for a couple pieces of non document papers, like 70$ for DHL. I don't want them to be overnight deliveries or super fast. I just want to keep a penpal because it seems fun to do

if any of you have the experience with buying postage stamps and sending items through liban post please let me know .
