First of all, it needs to be clear that "Eternal Life" is not a brand, but a manufacturer that once existed. Yongsheng Pen Factory, formerly known as Business Leading Pen Factory, was founded in 36 years 10, and later renamed as October Golden Pen Factory. 1987 was renamed Yongsheng golden pen factory, 1990 was approved as a national first-class enterprise, and 1992 was restructured to establish Shanghai Yongsheng pen making co., ltd., but after many reorganizations, the immortal data at present has nothing to do with pen making.
In the market, there are some counterfeit products, especially Pike 5 1, drei zweiдва due and other models, which are the hardest hit areas. Some imitations are even fake.
Therefore, it is necessary to be cautious when buying eternal life pens. If you buy a non-mainstream model or a foreign trade export model, imitators are more likely. At the same time, some imitations can also be identified in some ways. For example, you can check the ink bag protection tube at the inking place: if it is rotary inking, it is probably an imitation, because it is an extruded ink bag, which is durable. In addition, if the protective tube is frosted and made of aluminum, nine times out of ten it is an imitation.
