The "original" spring-lock metal label holder fits tightly over binder spine. Metal frame has a black rustproof finish to retain its fine appearance for years. Clear plastic windows protect the inserted label from soil and scuffing. High-quality steel spring wire clips provide positive grip and have a reverse bend to guard valuable papers from accidental damage and fingers from injury. Quality of design has made this label holder the one that remains in demand and highly useful in business today. Includes blank inserts.
