YKK® QuarterLock Snap®
This is a special snap button that can be simply locked by turning the cap part 90 degrees. Original designs and a wide variety of plating are available. For example, it can be used on a pocketbook or wallet, or on the cover or flap of a bag that holds important items, to add a simple locking function. We also suggest using it as a detachable part for the shoulder strap of a bag that can be used in two ways, as a shoulder bag and a clutch bag.
