Korda found that by using a small piece to cover the swivel on the lead it kept everything neat and tidy but more importantly offered much better camouflage. They are also the perfect size to fit over our Kwik-links and Stik-Klip. To fit, thread piece of line through eye of swivel or Kwik-link and then through sleeve, wet metal item with saliva and pull on sleeve. Sleeves may need to be cut down for some applications.
