The replacement rubber hooks for "Squid Rubber" come in three sizes as shown in the image: S, M, and L. Depending on the conditions at the fishing spot and the target fish, we recommend using different sizes. S size is recommended for weights between 45g to 80g, M size for 80g to 150g, and L size is suitable for larger targets and can be used for all weights. We encourage you to switch between the genuine rubber hooks and the "Squid Rubber" rubber hooks to enhance your fishing results.
