These are the same anklets and jesses that I use on my own merlins.
Anklets are made from lightweight kangaroo, machine cut, includes holes for grommets and slits along the edges.
Jesses are also lightweight kangaroo, 6" long. They have slits for a swivel and should be removed before free flight.
This kit will also include 2-piece grommets.
Please indicate whether you need for a female or male (jack) merlin.
