Modeling-compound sparkle typically comes from mica, while craft glitters and sparkly pom-poms are commonly made from plastic films such as PET (polyethylene terephthalate) and polypropylene.
Glitter glue pens are designed for use on paper, craft sticks, fabric, foam sheets and other common art surfaces used in kids' crafts.
Labeling varies by product, but many craft supplies are marked "Suggested Age: 6 Years and Up," while some items and certain children's goods carry a "Suggested Age: 2 Years and Up" warning—always check the product label for the specific age recommendation.
Sparkle and texture are added using techniques such as glitter overlays, high-density and puff prints, flocked lettering, screen printing, and decorative details like ruffles or glitter trim.
