Designed to work with White Caterpillar's unique Glow Bowl Flameless Candle system, this 18 fl. oz. gel refill will last for months with proper care, and has enough fragrance to scent a medium sized low-scent room. Use this White Tea & Ginger glow bowl gel in their glow bowl unit when you want to freshen up your home without using an open flame. Pour about half of this scented gel into the the glass jar and switch on the light. The light bulb will warm up the scented gel causing it to release the fragrance into the air. After about a week, you may notice the gel starting to dry out, simply add a little bit of water to rejuvenate the fragrance. When the scent becomes to faint throw away the gel and refill it with your favorite glow bowl fragrance.
