STILL ON ITS ORIGINAL 1950s PACKAGING with the words
" MODERN STYLE RING COMB KIN HIP METAL AND PLASTIC FACTORY HONG KONG AN AID TO BEAUTY CHARM AND GLAMOUR many hair styles are easily arranged with the Ring Comb"

The ring is in fact oval, bright red in colour, made of plastic, and is 8cm long and 4.5cm wide.
These were found in an old warehouse clearnace - some of the cards are a little bashed.
