Pack of one clasp. One VERY UNIQUE .925 STERLING SILVER toggle clasp with built-in, fancy oval-shaped cones (as seen in photo). Inside each cone is a "tying bar" that you can use to loop threads around to secure them when making multi-strand pieces. These clasps measure approximately 40mm from the end of one cone to the end of the other. The interior diameter of each cone is approximately 10mm from side to side and about 7mm wide.
