Great.
Little story behind the wire gauge sets and who developed them.
The members name, Sean Fogarty. Follow this link: Wire Gauge Sets
I found they can break easily as time goes by. You might want to coat the exterior of the head or gauge part of the device with nail polish or even use duct tape or some type of film over both sides of the gauge head. I have purchased 3 pair in 8 years I belive.
