As long as there are no obvious cracks and white marks, break the nib back slowly at 40℃ (no good words), but it must be slow.
If your hand hurts, touch the pen tip to the bottom of the basin in the opposite direction, and the same is true. Just dry it. Don't write too hard in the future to avoid the nib breaking due to memory.
Even if it succeeds, there will still be problems of writing difference and fluency. If you are not satisfied, or the maintenance is unsuccessful, the best way is to change a pen directly or directly.
A pen is a pen-like writing tool with a metal body. Pen ink (mostly black or blue) is filled through the hollow pen tube, and then written through the duckbill pen head through gravity and capillary action. It can be said that it is a writing tool of western calligraphy.
Most pens can be replenished with ink. Generally speaking, vials or straws such as eye drops are used to supplement the kit. The earliest historical record of fountain pen can be traced back to 10 century, and this earliest fountain pen has been used until 18 century. The development process was very slow, but it was not until the beginning of the 9th century that a pen with stable and accelerated flow was invented in the production process.
Only three key inventions have made the pen a widely popular writing tool. These inventions are: gold nib made of iridium, hard rubber and free-flowing ink.
