Wick Selection: TABBED #62 (4 inches) TABBED #126 (6 inches) Wick Selection Guide All of our wicks are lead free and the wax coating is a regular-melt, paraffin wax coating. These are designed to provide the benefits of a self-trimming wick posture w/rigidity approaching those found in cored wicks. High-performance fibers, along w/other natural materials are engineered into a specially constructed braid, producing a more predictable wick posture. Our wick is especially well-suited for tough-to-burn formulations that contain many additives. It is also an excellent choice for paraffin, vegetable & gel candle systems.These wicks are made from a blend of cotton & paper, are pre-waxed & tabbed feature a 6mm sleeve rather than the industry standard 3.8mm. The longer length means increased safety for glass containers. Please be aware that containers made from very thin glass or a lower quality of glass can crack from the heat of the wick. Larger the quantity purchased the cheaper the price.
