Query: Glass Wick-Holder Insert and Wick

I received a set of 12 with one broken in the package. The wicks are only about 4 inches long and are useless. The wick easily slips through the glass and needs to be rigged in order to stay in place. If not, can be a recipe for disaster.Be aware of the shipping costs. They are EXTREMELY INFLATED!
