Using these votives is easy. Simply place your Nexis LED candles or HD8 and HD12 liquid candles inside. Enjoy the warm, soft light filtering through the multi - colored bubbles. As these votives are handmade, remember that the color and texture might vary from piece to piece, which is part of their unique charm. When it comes to maintenance, gently wipe them with a soft, dry cloth to keep them clean. Avoid using harsh chemicals as they may damage the glass. Keep them away from sharp objects to prevent scratches.
