Ball Jointed Dolls (BJDs) are collectible, customizable dolls with articulated ball and socket joints, allowing for lifelike poses. Crafted typically from resin, they range in size and feature exchangeable parts like wigs, eyes, and makeup for personalization. Popular for their realism and flexibility, BJD enthusiasts often engage in photographing and creating detailed narratives for their dolls, fostering a vibrant community around this creative hobby. Though BJDs can be pricey, their potential for customization and the joy of storytelling offer a unique and rewarding experience for collectors.
