BLACKWING Volume 55 The Golden Ratio Pencil (Free Original Box With Every 12 Pieces)

NOTE: PENCIL DOES NOT INCLUDE BOX. BOX PACKAGING IS GIVEN ONLY WHEN YOU PURCHASE IN QUANTITY OF 12PCS. The Blackwing 55 celebrates the Golden Ratio. It’s a reminder to slow down and savor the beauty around us. Each pencil contains our balanced graphite and features a design inspired by the Fibonacci sequence, a series of numbers that approximate the Golden Ratio. The width of each color block is the sum of the widths of the previous two color blocks: 1, 1, 2, 3, 5, 8, 13, 21, 34, & 55. We designed it in millimeters and then scaled the design up to 1:1.175 ratio to fit the canvas of the pencil. A simple formula with a magnificent result.
