Product Name: Badminton Racket Wire Nails/Rubber Particles/Wire Sleeve/Wire Tube Material: high quality nylon Unit: grain Color: mix and match Model: different types of single wire hole, double wire hole Quantity: 3pcs Specifications: 10g Functional description: Special thread hole rubber particles for badminton rackets, also known as wire protection tube/thread nail, and the common saying "corns" is also used in some places. Thread tacks with different functions such as single thread hole and double thread hole are the system solution for racket thread tacks. No matter how good the line is, it needs to be protected by the line protection tube. After the line protection tube is worn out, the service life of the ball line will be greatly reduced, especially the high-end line with good elasticity and high price. Change the cable accessories, take care of our favorites, and use raw materials imported from Taiwan/Japan. It supports 10 common specifications and can basically replace more than 98% of rackets on the market. Careful golfers usually replace most of the cable protection tubes before threading to prolong the life of the racket.
