An unusual colour for a button ...if Farrow and Ball made buttons...
A soft dark grey, and a pleasing design.
A big star in the centre with little rays radiating out around the rim.
They are vintage catalin plastic,
I have them in either 12 on a card - 1.8cm, 2cm or 2.2cm wide,
or 24 of them on a card in 1.5cm.
