A selfie stick is a portable device that allows users to take self-portraits or group photos from a distance. It typically consists of a long, extendable pole with a holder at one end to secure a smartphone or camera. This tool helps capture wider angles and includes features like Bluetooth connectivity for remote shutter control. Selfie sticks are popular among travelers and social media enthusiasts, as they enable better framing and composition in photos. They come in various designs, some with adjustable lengths and built-in tripods, making them versatile for different photography needs.
