Writing instrument with biased rotatable assembly

A writing instrument comprising:

• an elongated shell having a longitudinal axis;
• an elongated assembly having a writing tip disposed at a first end of the elongated assembly at a fixed angle relative to the longitudinal axis and at an offset to the longitudinal axis and a weight at an offset to the longitudinal axis,
• the elongated assembly disposed at least partially in the elongated shell,
• the elongated assembly moveable relative to the elongated shell between first and second positions along the longitudinal axis, a locking surface of the elongated assembly abutting a locking surface of the elongated shell with the elongated assembly in the first position and the surface of the elongated assembly spaced from the surface of the elongated shell with the elongated assembly in the second position;
• and
• a cup-shaped flexible bushing having an annular flange at a first end and an annular disc at a second end,
• the flange secured between axially facing shoulders of the elongated shell and the annular disc secured between axially facing shoulders of the elongated assembly,
• the flexible bushing biasing the elongated assembly toward the second position.
