This stainless steel magnetic clasp will finish round cord up to 4mm in diameter. Great for leather, pleather, silk, and satin cord necklaces. Simply dab some glue inside the cord ends and insert the trimmed cord completely through to the end of the cap. We recommend Zap-a-Gap glue for most types of cord.
Measurements: About 16mm long (when closed) and 5.5mm in diameter. The cord ends are 4mm in diameter and about 7.5mm deep.
