This double stitch marker is both a ring marker and locking progress keeper. 

To use as a progress keeper, push the lever on the side of the fish to open the clasp. Hook the marker to a stitch in your work to highlight a stitch or note your place in your work. 

To use as a stitch marker, slip the attached ring onto your knitting needle, in between live stitches, to mark a specific place in your work. 

This listing is for one marker in your choice of color.
