Left out some items in JP post itemization list

Hey guys,
I'm in the process of shipping all my stuff back to my home country (Malaysia) using JP post by sea, as i'm moving back at the end of the month.
Unfortunately the first 3 boxes I shipped back I did not fill out all the items accurately for the itemization list as I was still struggling to figure out how to do it correctly.
I don't think any of the items that were in the packages are particularly problematic themselves (sfw anime figurines, stuffed animals, etc) , but I'm wondering how much of a problem it could cause in the near future that I had not written them down in the itemization list.
Does anyone have any insight or experience with this?
For context, I shipped those boxes about a month ago and haven't heard anything from the post office so far. (They haven't arrived in my home country either though since it's by sea)
