4mm x 5mm String-On Clasp with 1mm Silicone Grommet. Sold by the Piece. This is our smallest String-On Clasp. This clasp is barrel-shaped with a 1.0mm opening in the silicone grommet to securely hold the cording that you thread through it.
A string-on clasp is basically a stopper bead with a soft silicone grommet that won't damage any of your jewelry-making materials.
Made from hypoallergenic brass and electroplated nickel free. Our beading snake chain 0.7mm fits perfectly with this clasp.
We absolutely love how professional these clasps make our jewelry designs look and feel.
