K9 Optical Glass Rainbow Prism Beads for EDC Spinner

K9 Optical Glass Rainbow Prism Beads for EDC Spinner

Bring a stronger visual effect to your EDC spinner with these K9 optical glass rainbow prism beads.

Made from high transparency K9 optical glass, each bead is designed to create bright rainbow reflections and strong light refraction from different angles. When your spinner moves, the bead catches light and produces changing colors, making every spin more vivid and eye catching.

Unlike coated AB beads, these beads do not rely on a surface coating for their rainbow effect. The clean optical glass structure and internal four side refraction design help maintain a pure, bright, and long lasting color effect during normal EDC play.

The round bead design gives a smooth and clean look, making it suitable for a wide range of EDC spinners, fingertip spinners, and custom spinner builds.
