For leather: This size fits 1mm and 1.5mm leather.

Other uses: This size is an ideal bead bumper.  Place between beads in a strand to add color and protection.  Use with wire work as a buffer to hold larger glass beads in place. This size is popular for Fingerboard enthusiasts.   EPDM O-Rings were developed to form a waterproof seal.  They can be used with LED lights to form a waterproof seal between the bulb and hardware.  These have also been used for body piercings that often require a stopper of this sort, tattoo equipment, paint guns, bicycle & Industrial parts.

Sizing: The ID or Inner Diameter is the size of the hole.  Generally, choose an inner diameter slightly smaller than you require.  The rubber will stretch to fit over items and form a strong seal or hold items in place.
