This is the outer box that has an inner sleeve that slides out which contains the cards, the idea being, this box and the cards could be sent to potential clients as an example of the new Sirio Ultra Black paper which could be kept in the office/studio as an exampe of the paper's qualities and a nice keep-sake item that fits neatly onto a shelf. The outer part to the box is using Fedrigonis 115 gsm textured paper which i have screenprinted onto with the textures of feathers, and the inner sleeve says "Sirio Santuary" which ties in with the idea of a place for the birds and the collection of different paper stocks.
