Midcentury Royal Sylvania C7 Fluorescent Christmas Lights in

Midcentury Royal Sylvania C7 Fluorescent Christmas Lights in original box and includes original yellow light string tag (see pics).  7 working bulbs:  2 Coral, 1 Green, 2 Yellow, 2 Orchid. When the set is plugged in, the white bulbs assume their colors - and each is much more vibrant than I was able to capture in my photograph! Each bulb is marked with Sylvania and its color. Each light has its original "Royal-Klip."  The original box has a few small taped areas (see pics) and a separated box end (as pictured). Wiring and plug end looks to be in excellent condition.
This light set was only produced for 5 years, making it highly collectible. Introduced by Sylvania in postwar 1945, these fluorescent bulbs cost 2 1/2 times more than the standard Christmas lights of their era, and production ceased by 1950.  All bulbs and wiring are in working order prior to very careful packaging and shipping. Purchaser acknowledges the durability of vintage Christmas light sets cannot be guaranteed due to their nature.  Lovingly packaged and shipped FREE to buyer. Thank you!
