How to pick out a good bag? In fact, in addition to the fabric and feel, insiders often from some details, see a bag's real work.From this article, we will introduce some details that only the "insiders" know. From these details, we can clearly know how a bag is really made:

The zipper on the bag is composed of three parts, zipper, puller and TAB.The two sides of the zipper are usually made of nylon, and the "zipper teeth" in the middle are mainly divided into "rubber teeth" and "metal teeth".How to tell a zipper is good or bad?We can identify the following four points:

1. Check whether the "zipper tooth" falls off (minor points);

2. Pull the puller several times to see whether the puller and the zipper are connected smoothly;

3. After tightening the zipper, bend a part of the zipper to increase the strength. While bending, check whether there are any cracks (zipper teeth).

4, look at the bridge gap between pull card and pull head, if the gap is large, pull card will be easy to break with pull head!Because the pull is manually fixed to the pull head.
