The card says
The Lingerie Card
ARTIFICIAL SILK BUTTONS
Dainty & Chic.
Made in England.
18 LINES.
MADE IN POPULAR SHADES.
Colour: Purple
Condition: UNUSED. These buttons are unsold shop stock, probably dating from the early part of the 20th century. The buttons are in very good condition, with minor discolouration, though they are a little dusty. The cards are discoloured with age, creased, and a bit tatty round the edges. Please bear in mind that these buttons are old, and need to be treated genty and carefully, I do not know if they are washable.
