This line winder allows for easy line winding by fixing it to a table or other surface. It's convenient for replacing fishing line. The lever-type strong suction cup firmly attaches to desks, tables, and other surfaces, allowing you to wind line in a stable, fixed position without wobbling. It's very simple to use. Just insert the shaft into the line spool and wind the reel. The spring-loaded shaft accommodates various sizes of line spools. 【Specifications】 Size: Approximately 14cm Material: Aluminum
