These decorative and functional items, commonly found in a large retail environment, serve as a protective enclosure for candles. Their primary purpose is to shield the flame from drafts, preventing flickering and extinguishing, particularly in windy conditions. For example, a glass cylinder placed around a pillar candle provides a stable and consistent light source, even outdoors.
The utility of these products extends beyond mere aesthetics. They enhance safety by containing potential wax spills and reducing the risk of accidental fires. Historically, similar devices were used in maritime settings to protect lanterns during storms, demonstrating their enduring value in providing reliable illumination. Furthermore, they offer a versatile decorating option, adding ambiance to both indoor and outdoor spaces.
