SNOW DOME and SNOW GLOBE shakers have a liquid-filled glass or clear plastic portion incorporated into one or both shakers with glitter or snow-looking material floating in it. When the shaker dispenses the salt or pepper it puts on a snow display afterwards.
The older sets are almost always made of plastic and may have a variety of either souvenir site or Winter/Christmas designs. Newer sets often combine ceramic and glass with the globe sitting on a ceramic object base.
