What happens if you swallow the top of a felt tip pen?

Swallowing the top of a felt tip pen can pose a choking hazard, especially if it is a small piece. While the felt tip itself is generally non-toxic, the ink and plastic components may cause irritation or discomfort if ingested. It's important to seek medical attention if swallowing occurs, particularly if any adverse symptoms develop. In general, it's advisable to keep such items out of reach of children to prevent accidental ingestion.
