Dongmi pens not only look good, they write smoothly, they are quick-drying and cheap. More importantly, the unique craftsmanship allows the refill to be discarded only after 100% of the ink is used, so it is not used at all. I'm worried about wasting it like other pens that have a little bit of ink left and have to throw it away before using it up. It also has a large capacity and can be written for a long time. The quality is also very good and has a sense of weight.
Things to note when purchasing pens:
1. Ink: If gel pen ink is not properly stored during storage, processing, and transportation, various problems may occur. Therefore, please use a variety of test writing methods when purchasing, such as writing the number "8" continuously without interruption, "quickly circling" and other methods, which can not only test the smoothness of the pen but also see whether the ink is even.
2. Tail plug oil: It is divided into two types: refined from minerals and refined from petroleum. The purer the color of the tail plug oil, the cleaner the writing refill can be. It is very important whether the tail plug oil can follow well.
3. Wax ball: When pressing the gel pen, there is no pen cap seal at the front, so a wax ball is required. Please pay attention to whether it is easy to fall off. If it falls off, it is likely to cause poor writing. Ordinary gel pens The front end has a silicone seal inside the cap so no wax balls are needed.
4. Oil tube: The inner diameter of the refill oil tube is related to the capacity. The quality of the oil tube is mainly to check whether it is straight and hard, and whether the ink is used smoothly. Pay attention to check to prevent being cheated.
5. Silicone: The rubber ball that seals the pen tip. Poor quality or improper placement of the rubber ball can easily cause ink leakage and dry ink. Check whether there is a silicone ball placed flat inside the pen cap and whether the depth direction can ensure a seal. In addition, the elasticity of the rubber ball must be good.
6. Pen tip: According to the stitch thickness, it can be classified into four categories: 0.3, 0.5, 0.7, and 1.0mm. You should choose according to different needs when purchasing.
For example, 0.3mm is generally suitable for writing financial account records, 0.5mm stitch should be selected for exams, and 1.0mm stitch should be selected when signing documents for business cooperation; the pen tip can be classified according to the processing technology: bullets Head, gourd head, full needle tube, half needle tube.
