This is an antiqued brass finish roller buckle, suitable for use on a 12mm (1/2") wide strap.
These buckles are perfect for use on bag straps and pocket flaps and can be fitted with matching antiqued brass rivets or joining screws to complete the look.
These buckles are cast from zinc alloy (90% zinc plus small quantities of aluminium, magnesium and copper) rather than solid brass, so we do not recommend them for use on dog collars or horse tack.
