These 4mm fiber optic glass rounds deliver that signature cat's-eye glow in crisp white — a smooth, consistent bead that earns its bestseller status for good reason.

The fiber optic finish creates a soft, luminous sheen with a subtle moving light effect at the center, giving the white a depth that flat or opaque finishes simply can't replicate.

What to make with them

Their petite 4mm size makes them ideal for delicate strung bracelets and necklaces where even light reflection matters, and they work beautifully as spacers between larger focal beads in bridal or heirloom-style beadweaving projects.
