I believe they sent them out in April too.
I have checked that since there's no delay for sending from japan to malaysia, so i thought there will be no problem of custom checking since it is just mangas.
I want try to ask Japan post myself via email though, but it seems doesn't have the email address.
If you want to reach out to someone in Japan and you are available anytime, you can schedule a call between 6:00 am and 10:00 pm your time.
For diving and snorkelling on the west coast, you should plan a visit between November and August.
Does anyone also having or had the same problem as i am.
