Absolutely, it is perfectly acceptable to display candlesticks without candles. Candlesticks themselves are often pieces of art, crafted with intricate designs and made from a variety of materials such as brass, silver, crystal, or ceramic. They can serve as standalone decorative items that add elegance and sophistication to your space. This allows you to appreciate their aesthetic value even without the presence of candles. Moreover, displaying candlesticks without candles can be a safer option if you have children, pets, or simply do not want to worry about the potential fire hazard. Therefore, feel free to use your candlesticks as decorative elements in your event design, regardless of whether or not you choose to include candles.
