The basic issue in the Elastic Cord is the lines. The lines show the strength and Elastic Cordity of the Elastic Cord.

As Si-Mi Teks has manufactured to the world standard, we have given ourselves a debt to our valued customers to give this information.

As is known, if you are in Elastic Cord arm;

• If there is only one line, the product is worn with a single tire (covered with rubber); 100% stretch.
• If there are two lines, it means that the material is supposedly worn, the number is a single thick rubber, and it is 85% Elastic Cord.
• If there are three lines, it shows that two rubber tires are used and 70% Elastic Cordity.
• If there are four lines, it means that the material is supposedly worn, that three tires are used and that the stretch ratio is 60%.

It should never be forgotten; the desired line can be placed on the Elastic Cord, but it will be the same as the above-mentioned line on an Elastic Cord standard of the world standard.
