The invitation includes, an owl, a letter of acceptance to Hogwarts School of Witchcraft and Wizardry, a list of school supplies we will be collecting at the party, and a key to your Gringotts vault.
The key will be needed to get your Wizard Money. Then you will be able to buy your school supplies and treats at Honeydukes Sweet Shop!
The Owl Post is just about ready to send out the invitations!
Check out the Cauldron Cakes we will have at the party
