I am Very Happy with these buttons. They are about the size of a 60mm rotary replacement blade. They are sturdy and well-made (no sharp edges), and the holes are large enough to use floss, twine, or yarns. They are Large and perfect for the bag I plan to make which has a flap over the top that calls for a button closure. I am modifying the pattern to make it large enough to use for grocery shopping day.
