Vintage Two Tone Metal Cufflinks Goldtone Silvertone Brushed Striped Rectangular

Hello, you're looking at a vintage pair of two-tone gold- and silver-tone cufflinks. The design is a subtle stripe pattern that has a brushed look to it. They measure about 1 inch across. I am unsure of the metal used, since they are not signed or hallmarked on the back. Condition-wise, there is a general patina/tarnish to them along with some scuffing. There is also some discoloration on the front and back of one of them. Please see photos for more detail.
