A high-durability snap designed with a high-strength high-grade SUS wire shaped into a V-shape and wrapped around the end so that when excessive force is applied, the whole stretches and avoids the worst-case situations such as detachment and breakage is.

● Slide lock system and end winding process that expands and contracts when excessive force is applied
● V-vent design to prevent knot displacement and maximize strength.
● Use of high hardness SUS suppresses shape change and achieves exceptional breaking strength.
