An deep shiny mahogany brown colour with depths and variations within the colour, characteristic of this kind of vintage plastic.
There are deep concentric circles around the rims and a slight circular indention around the 2 thread holes in the middle- this adds interest, texture and light catching potential to the buttons.
I have 2 sizes 1.5cm and 2.3cm.
I'm selling them both in lots of 6 loose or the 1.5cn also comes on sheets of 24 and the 2.3cm on sheets of 12s.
