I found these buttons at an old button factory 

that closed years ago here in Muscatine Iowa. 

The new owners of the building are liquidating

 all of the old button inventory! 

These buttons are "new", never been used vintage! 

They are probably from the 1970's.

The buttons measure 9/16 inch.

 You will receive 10 buttons like the ones in the photos.

If you need more just send me a message!
