These brooches are super easy to use. Just find the spot on your sash or wherever you want to decorate, and gently press the pin through. The safety latch clasp will keep it firmly in place. When you're not using them, store them in a jewelry box or a small pouch to prevent scratches. Clean them with a soft, dry cloth regularly to keep that shiny gold look. Be careful not to drop them, as the rhinestones and pearls might get damaged. Also, avoid exposing them to water or harsh chemicals, as this could affect the plating and the materials.
