When selecting the spiral wire, we need to pay attention to its quality. Some of the loop wire will be cracked due to the fact that the surface of the coils is not strong enough because of the fact that the plastic layer is not strong enough. Too thin the coil will also cause problems such as unreliable binding. After the coil is locked, no more pages can be added unless the ring wire is removed.
The characteristics of the YO ring:
First, its envelope is generally made of environmental protection material kraft paper, because it is high strength and durable, making it the most basic requirement of environmental protection theme. Second, and the inner core uses recycled paper, which is used to purify and regenerate waste paper, which is good for protecting eyesight. It makes the coils of environmental protection have high cost performance.
