Vintage Light Bulb with E26 Base, 40-Watt (Pack of 6)

I have these bulbs in my set of string lights and they look awesome. This is the third year I’ve had them up and so far none have burned out but of course I do not have them turned on all the time as they are accent lights on my deck. I also live in an area where it gets very windy and have had no problems with the filament breaking.
