The Blackwing Volume 55 celebrates the golden ratio. The design of the pencil uses the Fibonacci sequence, a series of numbers that approximate the Golden Ratio in blue and grey. A perfectly balanced graphite with a classic pink eraser set in a silver ferrule. All Blackwing pencils also come in a 12-pack gift box that also doubles as a pencil cup.
Functional and elegant design- fun fact these timeless pencils were also RBG's favorite!
