Effortless Connection and Secure Knitting: Seamless join: The innovative design features a tightening slot for a secure and smooth connection, preventing snags and interruptions in your knitting rhythm. Three connector sizes: Each pack includes 3 connectors offering flexibility to tailor the cable length to your specific project requirements. Tighten with ease: The included cable key ensures a firm and reliable connection, giving you peace of mind as you knit intricate patterns and expansive projects. Important Note: For optimal security, always use the cable key to tighten the connector firmly onto the cable. A loose connection can lead to the connector coming undone and potentially unraveling your work.
