Perfect size to easily secure your wicks to the center of your containers. They are designed to keep your wick securely in place for a safe pour of your candle. They are pegged underneath so they do not slip and these pegs make them fit multiple size jars. Pictured is the same holder on a 6 oz jar all the way up to an 18 oz. jar. They will fit some smaller and larger jars. They are made in assorted colors so yours may differ in color. To inquire about having them custom made to fit a larger jar please contact us by email at crimsoncandlesupplies@gmail.com.
