This 4.5cm wide plastic tortoiseshell ring comb comes on its original Donald Duck shop display card
I am told by people that have used these that they are VERY effective !
The original price sticker shows they cost 29c
Some of the cards are a little grubby and bent from long years of storage in a warehouse.
If you want this for display rather than use - let me know and I'll send the cleanest card I can find.
