5 Strands of pure round sterling 935 Argentium tarnish resistant silver wire with 4 matching silver knots. All knots are the magic adjustable knots of Africa. While these are adjustable there is not as much play as on other models so you will have a better fit if you specify small (ladies or skinny men) or large (men or plump ladies). Men's will open to go over largest men's knuckles while small will close tight on smallest lady's wrists.
Notice these are fully rounded wire, and 5 strands in narrow parts, 10 when they overlap.

For Small sizes there is not much room for sliding. Until Etsy fixes bug about options please select Med and send note that you want small at checkout.
