In a strong light these bakelite buttons are a very dark green...in normal light they look dark brown.
They always look bakelite..
12 of them, 1.8cm wide, slightly domed, with a very deco design embossed on the top.
They come on a display card - measuring 16.5 by 10.5cm.
Printed on the card is "Washable and Ironproof" - as well as "Made in England" .
They came from an old button warehouse that I cleared.
