What are similar to straight pins but have a decorative glass or plastic bead attached?

The correct answer identifies corsage pins, which are indeed similar to straight pins but are specifically designed with a decorative glass or plastic bead on top. This design serves both functional and aesthetic purposes in floral arrangements. Corsage pins are often used to secure corsages or boutonnieres to clothing, adding an elegant touch while ensuring that the floral accent remains securely attached.

The presence of the decorative bead enhances the pin's visual appeal, making it a more attractive choice for special occasions like proms, weddings, or formal events, where style and presentation are important. Thus, corsage pins not only fulfill a practical role but also contribute to the overall elegance of the floral design.

Other terms, while they may suggest some form of pin, do not specifically refer to this decorative style or serve the same function in the context of floristry and formal attire.
