These are old brass button findings for creating your own buttons. They hail from the 1940s or earlier, but we think you could find so many other uses for them. They are flat backed with openings so you could easily sew or glue them onto your projects. Their surface is brushed with a nice pattern.
Each measures 1-1/8 inch in diameter by 3/8 inch high. They have some heft to them, so you can be sure that they will last a long time.
