A gorgeous 1920s display card of 4 "The Beauty" Wave Setting Combs. The combs are made of a flexible tortoiseshell plastic, gently curved. Two are 8cm long and two are 9.5cm long.
There are instructions on the back which promise "a perfect and charming wave will be the result" I found these in an old warehouse, some cards are in excellent condition, others are a bit grubby and some are damaged, see the last 2 photos . The combs are fine on these cards, but I have made them cheaper.
