Up your adulting game by sending a good luck card. It's the next level in card giving, above Birthday card but below Thank You cards.
I'm made from bitchin' sustainably sourced 340gsm paper, which makes me thick in all the right ways. I'm on the smaller side, coming in at 105 x 148mm but don't let that fool you, I pack a punch. I also come with my own envelope cos I'm swish like that.
