Surgical marker

A marking apparatus comprising:

• a housing comprising:
• a substantially hollow outer housing with a proximal end and a distal end comprising an end cap for capping the distal end of the outer housing;
• and
• an inner housing comprising a plurality of writing nibs mechanically constrained in serial alignment within the housing such that the writing tip of the forward-most writing nib extends through an opening at the proximal end of the outer housing, each of the plurality of writing nibs comprises:
• a writing tip comprising an ink selected from xylene-based permanent ink and crystal violet ink, the writing tip extending from a first side away from the writing nib in an axial direction;
• and
• a cavity disposed in a second side opposing the first side, the cavity configured to accommodate the writing tip of another writing nib,
• wherein the writing tips of the plurality of nibs are aligned such that the writing tip of a forward-most writing nib extends away from the remaining writing nibs in the serial alignment, whereby the writing nibs are removable from the serial alignment, such that removal of the forward-most writing nib exposes the writing tip of a next-in-line writing nib.
