The Unbranded Brand 6 Vintage Antique Brass Drawer Pulls Hardware Oval Seashell 3.5"x 2"

I've shown a photo of the measurements across the drawer pull and it is 3.5. It measures approximately 2 up and down. There are 6 of these and some of them are tarnished and have patina. I have shown a photo of each. Please feel free to ask any questions and thanks for looking!
