Tell us a date that is special to you (birthday, anniversary, adoption, memorial, etc) and we'll create a moon phase charm from that night. We've used a very high quality long lasting glow mixture which reaches full charge in about fifteen minutes of sunlight or strong florescent light (such as kitchen light or UV light---UV light will give a fast charging ultra bright glow). Gorgeous ice blue glow will diminish over time, but can be charged over and over again for years to come. Glows brighter and longer than traditional glow powders or paints.
