The listing, Vintage Button Cover Crafts (Metal) - Maxant has ended.
In this auction there are 3 unopened vintage packages of these "Buttons to Cover" Metal Buttons which the back of the pkg indicates can be used for "Doll eyes, animal eyes, pillow centers, button pictures...", and more, wherever your imagination leads I guess. The 1st pkg, top left, is labeled ADB-1, with 4 buttons size 30 and they are 3/4" diameter. The 2nd pkg has 6 buttons size30 labeled ADB-1R. It says "purchase this kit only if you have saved your pusher and holder assembly aids from our kit #ADB1," which is the one described above. The last pkg contains 2 large buttons, size 75, which are 1-7/8", as well as the "miracle holder" thingy.
