This 3D folding basketball court keychain features a transforming design that converts from a book-shaped pendant into a detailed miniature court display with a single motion. The folding mechanism operates in three simple steps: unfold the front panel, press down both sides, and close the book cover for compact storage. Measuring at a portable size, it easily attaches to backpacks, keychains, or bags for on-the-go use. The vibrant color scheme and interactive 3D structure provide visual engagement while serving as a fidget activity. The product is available in multiple themed variations, including sports courts, fantasy landscapes, and adventure settings to suit different preferences.
