I like to add special things in the boxes. At the moment I've got sweet cat and animal stickers from Pony People, lovely postcards by Cara Carmina, mini stamps from Moosmade and I'm looking into the amazing postcards by Petite Miri. Do you, as a designer / illustrator / creative person or shop, have something that will be a perfect addition to the snailmail box? Email me (ankepankedesign/gmail) and we'll talk.
Keep in mind that it can't be too expensive (wholesale prices) or heavy. I'll also need about 25 pieces. When I use one or more of your products, don't forget to also include some business cards, I will put those in the box too.
