They’re extremely quick and easy to add or remove from the main line, without having to re-tackle. You just slide the line in or out of the central bore using the micro fine slice along one side that can be easily located using the small recess/guide set along the back edge of the backlead. You can pay with Paypal or Credit Card. Small items are sent with Royal Mail and larger parcels with my Courier.
