Glitter describes an assortment of small, flat, reflective particles. Glitter particles reflect light at different angles, causing the surface to sparkle or shimmer. Glitter is like confetti, sparkles, or sequins, but somewhat smaller. Since prehistoric times, glitter has been made and used as decoration, from many different materials including stones such as malachite, galena, mica, insects, and glass. Modern glitter is usually manufactured from plastic.
