This is a set of a notebook and box from Smythson, a luxury stationery brand that is a purveyor to the British Royal Family. Smythson is an established brand founded in London in 1887, known for its high-quality stationery and leather goods. The pale blue box and paper, as seen in the image, are called "Nile Blue" and are one of the brand's iconic colors. It also excels in functionality, such as "Featherweight Paper," which is lightweight and resistant to ink bleeding from fountain pens. It is beloved by celebrities around the world, including Queen Elizabeth and King Charles, as well as Grace Kelly and Kate Moss. This was received as a novelty item from AUDEMARS PIGUET.
