12 Antique Metal Candlestick Bulbs with Color Fluid in glass Xmas Ornament Light

I inherited these ornaments as part of my uncle’s estate. There are 12 antique ornaments with color fluid inside a glass bulb. Seven of them have metal tops, five of them have plastic tops. They measure 4.5 inches in length. Fabulous art deco design on the base and meant more for display than function. ? Please let me know if you have any other questions! They are absolutely beautiful.
