Each handle is marked with its size (2.0–5.0 mm) for quick identification, and the set supports replacement tips via a 2.0 mm hex wrench. Best for users who value precise size labeling and easy interchangeability. A potential limitation is that some users may require longer reach for deeper pockets in certain chassis.
