These mini chime candles are great because they are small enough that they don't take up much space on the altar, they burn down clean and don't leave as much of a mess, are great for travel, and they can be used up during one or two rituals.  4" each. Sold in singles or bulk packs of 20.

Blue: Emotions, healing, overcoming hard times, academics/study, the element of Water (West) and the Goddess.
