Created as a cross between a Pantone shade card and a stationery set, the Pen Fan fits 8 different flat-head sketch pens in a small, easy-to-carry set. The flat pens are connected to each other, forming a neat Japanese-fan style layout that displays all the 8 colors for you to pick and choose from. Each individual sketch pen is detachable too, allowing you to snap off and on pens to create a palette of your choice! Stationery-hoarders, you’ve been warned! More here.
What a brilliant design, love the way they are attached to each other.
