Since we are given items such as the Toy makers Bag for holiday events we need a bank specifically for these items. As well as have them to never be able to be lost or destroyed. A example of how this could be done is how Jagex does the same thing with Runescape. We could have a vendor who has all you holiday items with him and if you lose them or destroy them, you can easily retrieve them. 1 vendor could be placed in all 6 major cities and allow storage and retrieval of holiday items such as the Toy Makers Bag.
