I have seen these called by a variety of names; “flash extension cords”, “flash patch cords”, or simply “flash cords”. Whatever the name, the purpose is to allow you to use your flash off camera to minimize “red eye”, to light the subject from an angle, to provide supplementary fill light, etc. The straight one is about 22 feet long and the coiled one is about 2 feet long, fully extended. Both are in excellent condition with clean contacts and no visible wear.
Price is $16.00 for the pair plus mailing via USPS. I will accept paypal, cash, a check, or a USPS money order.
