This little ball is beautiful both day and night. During the day, you have the gorgeous 925 Sterling Silver coloured with yellow swirling enamel. And by night this ball lights up and glows in the dark for a long time. Mix and match with your favourite themed charms, or simply string with other glow in the dark charms for a complete glow in the dark bracelet. This is part of the Zookkie Collection and so it is engraved with the Zookkie logo!
