Abstract

A writing instrument having a writing point that responds to pressure applied during writing through the use of a cushioning element integrally formed with another component of the writing instrument. In a preferred embodiment, a writing implement includes a barrel, a refill with a writing point, and an end plug having a cushioning element integrally formed with the end plug. The cartridge may be retained in the barrel by the cushioning element attached to the proximal end of the barrel. The end plug may be shaped by an injection molding process. The stop element may be arranged such that compression of the cushioning element is inhibited or prevented after a predetermined degree of compression of the cushioning element. The cushioning element may have a variable spring rate.
