The large beads in these stitch markers are rounds of tiger eye (stone) dyed a lovely dark blue, with glass accent beads in iridescent-frosted purple. The end marker has one accent bead as a shiny almost-sphere instead of a frosted cube.
These stitch markers are made with black beading wire. I can’t guarantee them as snag-free, but the ends of the wire have been filed as smooth as possible, and they should not be a danger to your knitting.
This listing is for a set of 4 stitch markers. The 6-mm (US 10) needle is shown for scale only.
