Approximately 9x2.5x4mm sterling silver plain pinch bails, 1-1.5mm loop. These bails have a side-to-side hole alignment, and the given measurements include top loop. JBB Findings is internationally known as a manufacturer of quality silver bails. Manipulate the bail gently to find your best fit.
This sterling silver bail is listed as a "Plain Bail", but I'd call it Classic". I have not yet used it but it is a true staple in my jewelry findings supplies box. I'd recommend anyone looking for a classic, sterling silver prong bail to check it out.
