These stitch markers feature a tiny glass bauble filled with pearlescent white nail caviar (teeny tiny beads). They're really durable, good quality glass.
Silver colour top, leverback fastening. Other colours are available, as well as baubles with teeny stars in, little beads, and rhinestones. Please see this collection for availability.
Listing is for one marker.
As always, colours may vary based on the colour settings on your device, though I don't apply colour changing effects to my photos, so hopefully you'd be as pleased, or more, with it in real life.
