Crafted with top-quality UV resin, epoxy resin and glow-in-the-dark mica pigments, this grinder is as cool as it is functional.  Leave it in the sunlight (does not have to be direct) and it glows nice and bright when it's dark! You can enjoy its full potential anytime, anywhere by using the FREE UV flashlight to give it a quick recharge; 30 seconds or so.  Don't let the white part fool you because in the dark, it glows a beautiful greenish yellow color! The incredibly sharp teeth and smooth-spinning mechanism make grinding your dried herbs a breeze. Perfect for the free-spirited soul, this one-of-a-kind grinder embodies the vibrant essence of Unapologenx—handmade with joy and an unwavering commitment to quality and individuality. Elevate your herb experience with this brilliantly designed and efficient tool!
