First, the most taboo in using a brush is to let the ink harden on the brush hair, which is almost a punishment for the brush.

Second, don't use a pencil case. In the process of putting the pen cover, bristles are often hurt, and humidity is the killer of bristles.

Third, don't put the wet pen in the pen roller for too long. After a student left it for two months, his pen hair was broken like a dog. It's really scary.

Fourth, hang it on the pen rack to dry after washing. Some friends will suffer from the accumulation of ink in the nib and its hardening after air drying. If we can let the bristles lie on the toilet paper after washing the pen, dry them for eight minutes and then hang them on the pen rack, there will be no such trouble.

It's normal for brushes to lose hair. Of course, if it keeps falling, there must be something wrong. Don't buy those that are too cheap. Go to a slightly more formal shop. These should be of good quality. .
