A means is disclosed for marking one or more clean line on the absorbent tip of a cotton swab. The means comprises of a tool with a thin groove wherein at predetermined locations at the bottom of the thin groove, there are channels for directing ink into the thin groove from an ink source. A thin absorbent thread is placed into this thin groove to absorb and distribute the ink thereby allowing controlled distribution of the ink which results in the formation of a clean line when the absorbent tip of a cotton swab is rotated over the thin absorbent thread during the manufacturing of the cotton swab resulting in a clean line marked on the absorbent tip.
