1.HTP wick is a cotton wick interwoven with paper fibers for increased rigidity. A wellrounded wick that combines the structural strength of a paper core wick with the performance and even burn of a zinc wick. HTP wicks work well in paraffin, gel, and soy waxes. These HTP wicks are from the manufacturer, and may not behave the same as previous manufacturer. Testing is highly recommended. 2.Our wicks for candlemaking are made up of single flat Braided organic cotton wick with paper threads woven into the cotton. It has 6' length with 20mm base and neck length of 6mm. Made of clean, nontoxic materials, so no smell is emitted when burning.
