That's what my little girl said about these little babies! Three little cobalt insulators that I have heard were either tree insulators or electric fence insulators. I understand they attach to little J hooks. You be the judge. I have never seen any in use. They all look mint to me. $6 each plus shipping or $15 for the lot plus shipping. Thanks! One gone! Two left. $6 each plus shipping or $10 for the pair plus shipping. Thanks!
