The case-hardened Turian is made in plain steel and locks with a small allen screw. 5/16" solid steel stock is hand bent, polished and then case-hardened. This gives a unique look, varying from blue to mottling of black. It is prone to rust however, and should be dried if gotten wet. Some people will put a coating of mineral oil or wax on it to protect it. The case-hardened Turian is more specific look and is often worn by the more reserved person.
Each collar comes with 2 keys and two replacement screws.
All sizes are given in inside dimensions
