measurement given is the length of the barrette back from end to end.
You can use these barrette backs to glue, solder or sew things on to. French
auto-lock barrette backs are of Superior quality and meet EU Nickel
directive.These have pronged holes for more secure gluing. Do not be fooled by other sellers offering very cheap "French Style" Chinese imports. These are made in
France. All will be stamped "made in France" They have only two parts to
them, the barrette back and the hinged clip. Chinese copies will NOT have the "made in France"
stamped on them. You will find the Chinese version also have three
separate parts, they tend to break and are made of a weaker steel.
