1. The invisible zipper has "out-of-teeth" or "skewed" phenomena. The bad teeth can be removed, new teeth can be added, and it can still be used; when the invisible zipper head is pulled up, the teeth on both sides do not close together, which means that the zipper head is loose after wear , You can use ordinary pliers to gently clamp the closed end of the invisible zipper head horizontally, and it will become better immediately, and the teeth on both sides will be tight and no longer loose.

2. If the invisible zipper is not smooth, use candles or leather wax on it to improve the effect. If there is a little denitrification, you can use color matching skin cream to add color or use white electric oil n-ethane to lightly wipe the denitrification area to remove the stains on it.

3. If the invisible zipper has poor slippage or cannot be pulled, the general reason is that its size is too large and it does not match the size of the slider. In this case, the zipper needs to be adjusted and re-matched.

4. When opening and closing the invisible zipper, the corn tooth zipper may not be able to move because the slider is caught in the cloth. At this time, if you blindly pull the cloth, it will only make the cloth tighter. Therefore, Bright Technology recommends pulling the cloth stuck in the slider as much as possible and then pulling the slider back to its original position. If it is completely stuck, Don't use too much force, just pull up slowly. In addition, pay attention to the smoothness of sewing when sewing corn tooth zipper.

5. If the pull tab in the zipper head is accidentally damaged, the best solution is to find an old zipper that has been put aside, remove the pull tab, and install it on the new zipper. In fact, the most critical part of this time is the method of disassembly and assembly of the pull tab. Use a screwdriver or other pointed object to pry off the pull tab lock of the old zipper, and then remove the pull tab lock. This is also the case when the pull tab is installed. When the zipper pull tab is installed, buckle the pull tab lock back to the zipper body.
