Wonderful quality folding deployment clasps. They come in 5 sizes (12-14-16-18-20mm), and 2 colours (polished stainless steel or polished yellow gold-plated steel). These buckles are designed for the style of straps where the tail of the strap folds and slides under the shorter end of the strap, negating the need for pin holes or strap keepers. Choose from the drop down menu and do not hesitate to contact me for any questions you might have. These buckles fit the straps you see in the last photo and which are listed separately in the store.
