This winding is a flattened hollow rope, which is made of one material: NiCr, Kanthal, Stainless steel. The number of wires reaches 12 wires of the same cross-section, which allows you to achieve maximum taste transfer. The perforation of the cord allows you to transfer the liquid from the wick to its surface, which, in turn, affects taste properties. In addition, the perforation extends the service life of the wick by two to three times. Anyone who likes dry steam in MTL devices is simply obliged to have VB cords in their collection.
