These are old brass button findings for creating your own buttons or sweet clothing adornments. 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. They also have a bendable hook that can easily be used as the shank or you could flatten it if you choose not to use it!
Each measures 5/8 inch in diameter by a 3/8 inch high brushed dome. The shank will add a touch more height. They have some heft to them, so you can be sure that they will last a long time.
