These stitch markers are very lightweight and slip easily from needle to needle, up to US 8/ 5.0 mm., the size they are hanging on in the first picture. I won't claim that they are 100% snag free since they are constructed with wire, but the ends are safely nestled against the bead to minimize the risk to your precious knitting. These markers have been treated with a water resistant sealer, but are not water-proof, so please refrain from knitting with these in the bubble bath, hot tub, etc. The set includes 1 each of the markers as shown, though yours may actually be from another set. If you'd like a set to fit larger needles, or possibly a larger set for a big project, just convo me.
The markers will arrive on a small binder ring so they don't get separated in your knitting bag. You can even clip them right onto your project.
