These buttons are unsold shop stock, probably dating from around the early part of the 20th century.
The buttons are in very good condition, with very little discolouration, though a little dusty.
One of the pink buttons has come off the card, and been re-attached.
The cards are discoloured with age, creased, and a bit tatty round the edges.
Some of the cards have stains.
Please bear in mind that these buttons are old, and will need to be treated gently and carefully.
I do not know if they are washable, or if they would rust.
