Fill a PC many postage stamps INTERNATIONAL

I saw this beauty on a friends instagram (iheartmail on IG) and I just loved it. This is open to international users. Use a low denomination if you're going to use one type, but you can use various denominations if you'd like. You can add a note if you have room, or just send it with tons of stamps. You will have two partners in this round. If people like this, I will do it on a weekly or bi-weekly basis. If you have time to get it hand canceled that would be great, so the post man doesn't just scrabble with a pen on it (which they commonly do in the US, not all the time but they do it).
