Adorable and functional, this 3D printed light up Cat ring is great to have on hand in a pinch. In the daytime, it can be worn as a great kitten accessory by any cat lover. In the night time, twist the kitty face and let the bright 1 watt LED guide your way. Awesome for camping, festivals, treat or treating, or just to find your keys at night!
