https://hololivepro.com/en/question/tl;dr You have to email them to get permission to send anything but a regular letter and even if you just send a regular letter in an envelope, they can still just decide to throw it in the trash instead of forwarding it to Ame for any reason or no reason at all.
My post office said it can take up to 30 days for delivery, so try to get it in the mail before the end of the month.
