Wax play is the easiest way to add temperature to the bedroom, and these candles add a glow to go with it. Drop the lights, flip on a blacklight, and every drip turns neon on contact. The UV Blacklight Reactive Heart Drip Candle Set packs three neon heart candles that melt between 136 and 140 degrees, warm on the skin and made for sensation play instead of burning. A fun pick for temperature play, date nights, and couples who like a little show with their sensation.
