Pantone is a name very well known to anyone working in, or with an interest in, design and print. They define a standard system for specifying colour that's used all over the world. Tell your printing people or product manufacturers you want a cheerful shade of yellow, and you might get something different depending on who is interpreting it. But specify Pantone 13-0647, and you know exactly what colour you're going to get.
Now Pantone have brought their love of colour to a range of accessories, including these lovely stationery items.
