The Solder Wick is made of 100% thin pure copper wires and entangle or braided together for collection of unwanted solder in Circuit Board or Soldering Iron Tip. The entangle copper wires form a matrix of wire network, the entangle wires provide numerous holes and locations for solder to adhere onto the copper wires. It effectively adheres molten solder and clean off unwanted solder from PCB circuit boad. * Pure copper for effective absorb of Molten Solder. * Entangle Copper Wire Mesh of 2.0mm width. * Keep and roll up in a easy to open and keep PP Casing. * Total Length of wire mesh 1.5 meters. * Safe and Avoid destruction of copper thread on PCB board during clean off unwanted solder.
