An interesting colour - the colour of Red Coral according to the 1821 Werner's Nomenclature of Colours, used by Charles Darwin to describe the colours of creatures he found on his voyage on HMS Beagle. Its a "scarlet red with a minute proportion of reddish brown."
Anyway, Darwin aside, they are 1.8cm wide and a classic 1940s plastic design.
I'm selling them in lots of 5 or 6.
