12 of them come on a display card - measuring 8.5 by 11cm.
Printed on the card is "Washable and Ironproof" - as well as "Made in England"
For the 2.2cm buttons - I just have 1 half card of 6 left now.
I found them in an old haberdashers warehouse.
Some of the cards are a bit foxed from long years in storage.
