The elastic band has good quality and has three strokes.

　　The elastic band is common in our daily life, and everyone is very familiar with it, but you may not know the quality of the elastic band. Here are three tips to teach you how to distinguish the quality of the elastic band.

　　1, look at the elastic foot, normal good elastic band tension at least between the original length of 1.8 times ~ 2.8 times.

　　2, look at the durability, poor elastic band is easy to lose flexibility after a period of time. A good elastic band needs to be used when it is pulled for the longest time, and the difference is easy to stretch. So we have to choose a stronger elastic band to be more durable.

　　3, look at the shrinkage, just bought the elastic band soaked in hot water for about half an hour, shortening the elastic band within 8% of the length is better.

　　Did you understand through the above introduction? I hope everyone can use it when choosing an elastic band.
