These 8 oz. jar "Smelly Jellies" are perfect for locations that a candle or tart warmer are not an option. The water absorbing crystals allow for long-lasting fragrance. The cute daisy cut-out lid allows for ample scent throw in a variety of room sizes. When the crystals begin to dry out you simply add a little more distilled water to the jar and these will last for 4+ months!
