BLACK CODE string will give you spin and comfort.

The technology for manufacturing monofilament is based on 3 essential points:

The quality of the materials offered depends on the desired benefits. The Thermocore process. Specially developed by Tecnifibre for manufacturing polyester monofilaments to soften their natural stiffness. This requires a series of heating and cooling stages throughout the stringing process. This exclusive process reduces the polyester's stiffness, making it more comfortable to play with and less likely to cause injury.

The final structure of the string can be round, pentagonal, or even square in order to increase the effects through friction.

• Composed of 100% Co-polyester with a pentagonal structure.
  
• Recommended tension: 22-25 kg Maximum tension: 32 kg
  
• The copolyester material used will generate control and resistance.
  
• The pentagonal structure offers the ability to generate a lot of spin, allowing for extremely aggressive trajectories: deep, looping shots or short cross-court shots. A very effective arsenal on the court.
