This is a vintage box of 10 red and green GE Mazda Christmas tree bulbs, designed in a cone shape. GE stopped using the Mazda name in 1945, so they date around or prior to WWII.
These were purchased at a sale, so we do not know the history. There appear to be 5 red and 5 green bulbs, we can't date all of them to this box. Selling as is.
Perfect for collectors or those looking to add a nostalgic touch to their holiday decor, these bulbs offer a unique and classic design.
