Grab yourself a collectable sorting hat or 3 or 5! Its up to you but you can collect them all! The mystery grab bags will come in sizes of 1,3 and 5 so you can grab as many or as little as you'd like and there is even a Facebook page to show off your collection and trade them for others too!
Each grab bag will have a folded book with your pins in and also a picture of what you can collect. And with this you will also receive an A6 velvet covered backing card to show them off in your collection.
