1. Good quality at a rock-bottom price
2. Strong and durable
3. The tool is simple and easy to use.
4. Small and beautifully designed.
5. Strong practicability
6. High performance price ratio
7. Long life, small size
8. Practical and portable
9. Professional and technical
10. Nickel copper nickel is through three layer treatment to get the good rust prevention and corrosion resistance. The effect of nickel plating is better than those of single layer.
