This set comes with two slotted D-rings and a single loop bar end. To use this clasp simply attach as many strands to the D-ring as will fit. The two ends are brought together by attaching the bar end to one D-ring with jump rings (not included) or wire wrapped beads. The second side of the clasp is secured by feeding the bar into the D-ring itself.
Toggle bar measures 29.5mm x 4mm and its loop has a 2mm inside diameter hole.
