Lot includes both vintage and modern buttons.
There are many sets.
Sizes range from shirt buttons to coat size.
Some are metal, some plastic, some mother of pearl. (Those are the only materials I san identify.)
I haven’t picked out my “favorites”. The only ones I saved were the leather buttons for my Irish sweaters.
I can’t even estimate how many buttons are included. I hope the photos give you an accurate idea of this assortment.
