Now this will give you that nice and romantic glow. You can set up a romantic dinner with biohazard candles scattered all around. If that doesn’t set the mood, then nothing will. Although you’ll have to make do with just one of these, since that’s all that’s in stock right now. The Biohazard Glow In The Dark Candle is 3 ½ inches tall and 4 inches at its widest point and has a nice fresh green apple scent. You can purchase it for $9 from Etsy.
