Every two months, you receive a box of 7 - 11 items.
Homemade and professionally printed.
Posters, postcards, stickers, stationery, letters, tickets, permit, etc. Anything that can be imagined to have existed in the Wizarding World will be in the box. Be prepared for surprises as we'll extend the Magical World. After all, there's more than the UK Ministry of Magic in the world and Hogwarts is not the only school of witchcraft & wizardry ;)
Rest assured it is not just about paper craft. There are also goodies such as seals, mugs, badges, magnets, figurines, etc
