This is an early model of Wild Country Friends. These are the so-called "bar friends." I've checked them and they move without issue, but they are old, so please be aware of that and inspect them before use. Set of 4, sizes: #2, #2-1/2, #3, #4 Please understand that these are used climbing tools, and that any accidents resulting from their use are your own responsibility. Also, no claims and no returns are accepted. I am not considering selling them individually, so please understand.
