4 Plastic dress buttons turquoise vintage shank backs for sewing crafts hc2536

This lot of 4 matching buttons are turquoise plastic and 1 inch in diameter. They are triangles incised inside circles. These are dimensional buttons, not flat. They have metal shank backs. These are vintage buttons and have been used as one had thread attached to the back of one.
A note about the color. They are deep turquoise leaning towards teal. They definitely are not gray which is how they appear on my screen.
Please note that button purchases can be combined to save on shipping. At least 3 lots,often more, will go for the one shipping rate. I automatically give refunds when lots are combined.
