Nowhere on the instructions are the inserts even shown, so I'm not sure exactly what they are intended for

This is super simple and allowed us to get the line on nice and tight

Haven't casted yet for tangles but seriously doubt it will

Growing up I was always the one that had to help with spoiling the fishing line by holding it on a pencil

Gift for the grandson he loves it
