VTG lot MOP abalone shell buttons 9 dyed black/blue sew through small carved

Description

These are all mother of pearl shell buttons that are 1/2 an inch in width.  Please look at photo number 4-  these are over 3/8 of an inch and under 1/2 of an inch.
There are 9 of them here.  Nicely carved in a circle pattern.
These are not the buttons that you will receive-  These are the photos of a representation-  I have many lots of the these same buttons.  These have an excellent luster.  The color in the photo may look almost completely black. There is some luster in these buttons, so there is some color change-  it looks a little bit of some very dark midnight blue in there.   Since this is a vintage/antique button that has been dyed, I don't know how it will hold up to our modern washing machines.  Also if you are using these on something that will be washed I would rinse these and see how the dye holds up before using them- I don't know if the dye runs?  I'm trying to cover all my bases!
I will combine ship.   Thanks for looking.
