Abstract: A writing instrument attachment includes first and second band portions and a coupling mechanism. The first band portion include a first inner surface defining a passageway along a longitudinal axis and a first outer surface having a first outer radius that encompasses the first inner surface. The second band portion is integrally affixed to an end of the first band portion. The second band portion includes a second inner surface defining a chamber along the longitudinal axis having an inner radius that is greater than the first outer radius. The coupling mechanism includes a groove located at a first position on the second inner surface and a tab located at a second position on the outer surface. The first position and the second position are collinear.
