From Charles & Marie; home of always cool stuff:
"By now you should know that we are suckers for all things smart and helpful and this is another prime example! Such a smart contraption – and so simple! It’s a clip that you can attach to pretty much any notebook or folder or diary of your choice and once done so, you can attach your writing utensil of choice to it.
It is such a simple idea, but so amazingly clever! .."
