Coil-bound journals are notebooks that feature a spiral binding made from a continuous coil of wire or plastic. This design allows the pages to lay flat when open, making it easier to write or draw. They come in various sizes and styles, catering to different needs, such as note-taking, journaling, or sketching. These journals often have a durable cover, which protects the pages inside. The coil binding also allows for easy flipping of pages, and users can add or remove sheets if needed. Coil-bound journals are popular among students, artists, and professionals for their versatility and convenience.
