Glitter is the wor used to describe an assortment of very small (roughly 1 mm²) pieces of paper, glass or plastic painted in metallic, neon and iridescent colors to reflect light in a sparkling spectrum. Glitter is usually stored in canisters somewhat similar to salt shakers, which have openings that control the flow of glitter. These canisters may contain one or many colors. It is not to be confused with confetti, which contains larger pieces, nor sequins, which are larger yet. Glitter is commonly used in craft projects, especially for small children and sorority women, because of the brilliant effects which can be achieved relatively easily. Glitter is commonly used as an element of Christmas decorations, and can be added to rubbers and plastics. It is also often put into cosmetic products like lip gloss and eyeshadow. Glittery cosmetics are most popular among teenagers, but are also worn by older people, notably in the disco scene.
