12 bakelite brown buttons
effectively moulded to look like interlocking threads ...
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"
I have them in either 2.2cm, 1.8cm or 1.5cm wide
They have a single integral shank on the back.
