From the manufacturer:
Stretch Magic(R) Silkies Bracelets are made from silicone so they're light and feel smooth and silky against the skin. Bracelets are 6.75 inches (about 17.15 cm) long. Stretching can accommodate some larger wrist sizes, but fits best on wrist 6 inch (15.24cm) or smaller; 6.5 inches (16.5 cm) or smaller if worn with beads and charms. Cord is about 2mm (.08 inches or 5/64 inch) thick. The Silkies feature a special insert clasp closure for easy wear and removal. The easy-clasp is ideal for those tired of struggling with lobster-claw clasps. This item is latex free. This package contains fifty-six assorted bead and three silkies bracelets.
