Lifeline bath diffuser set

Lifeline bath diffuser set. Great gift or for yourself! Set of two diffusers float in the tub. A flameless candle. gives some light. It illuminates when it's placed in water. It's waterproof and water safe, according to the box. There is a reusable aroma diffusion ring. It includes an essential oil blend with their patented pump. I would think any essential oil works. Made by the same people that make Melissa and Doug toys. Missed the return window. NWT.
