265 Rainbow Niobium Lace Omega

Rainbow colored omegas. Yes, this is for real. The wire has been anodized in rainbow colors, which means the colors are not painted on and they're not some kind of plastic shielding. The colors are PART of the metal. They're not indestructible, though. You'll scrape the color off if you're REALLY mean to you markers, like rubbing them against concrete or something.

Designed for crochet, but they also work well for knitting row markers, and fit knitting needles up to US size 7 (4.5mm).
