Sorry folks, was out of state picking up some rescue animals (got an absolutely amazing Argus monitor!), and didn't see the thread below. I re-uploaded the photos. These leashes work great with all kinds of lizards. We use them on iguanas, cyclura, BD's, monitors, tegus, etc. I don't use them often, usually only when in a public venue such as a show or educational presentation, when I need to know that I have extra control. Barrel clasps and cording can be purchased at most sewing departments. I get mine at Walmart..the clasps are 2/$1.69 and the cording runs about $.40/ft.
