Abstract
A refill is provided that is packaged in a recyclable assembly of recyclable plastic and recyclable paper or cardboard. The refill is further constructed from recyclable plastic and uses soy resins for the ink. On a barrel of the ink refill is a graduated scale indicative of the amount of writeout of ink remaining in the pen. In addition, a follower, such as a floating ball or chemical chaser, clearly identifies the level of ink remaining in the refill. The assembly may further include a scale corresponding to the scale on the refill and may further include information relating to the recyclability utilization of the assembly and refill.
