| 120 | Ferrule designs differ in how the closure is later opened. A plain ferrule fully covers the stopper and must be removed with a decapping tool. A flip-off design carries a plastic button over a pre-cut aperture, which is lifted away to expose the central area of the stopper for needle penetration while leaving the crimp intact — the arrangement almost universal for injectable products and for research peptide vials. Colour of the button is a manufacturer's identification device with no standardised meaning, and it is not a reliable indicator of contents.{{r|iso8362_5}} | 120 | Ferrule designs differ in how the closure is later opened.

| + | 122 | Two consequences bear on handling. Once a flip-off button is removed, the exposed stopper surface is no longer protected, and its disinfection before each penetration is the compendially expected practice for multiple-dose containers. And the crimp is not intended to be removed and replaced; a vial whose ferrule shows evidence of having been decapped and recrimped has an unknown seal history, which is a recognised indicator in the examination of suspected [[Repackaging|repackaged]] or [[Counterfeit peptide|counterfeit]] material.{{r|usp1207}} | |
