These buttons are unsold shop stock, probably dating from the early part of the 20th century.
The buttons are in very good condition, though a little dusty.
The card is in good condition, though dusty and a bit tatty round the edges.
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 need to be removed before washing.
