Simply install the wick into your lamplight burner and your lamp will perform like new. Add interest and ambiance to your oil lamp's flame by trimming the wick to produce a customized flame. Trim the wick edges on an angle making a triangle to produce a peaked flame, round the edges to make a domed flame, or shape the wick into two triangles for a double peak flame. These easy-to-use all-cotton wicks are designed to burn evenly and efficiently draw fuel upward.
