lamy is basically free of fakes in China, and I advise you not to buy it at the counter, because it will kill people. You said that this lamy pen you saw on the Internet costs about 15 yuan. Then this pen is probably a hunter series. And if you are a student, this series of pens is very suitable for you. There are positive pen grip, piston inker and visible ink window. It is normal to sell online for 15. However, if you want to have some requirements on the material, I can recommend the Star Series, which is basically consistent with the internal structure and nib of the Hunter Series. Except for the material, the Hunter is ABS plastic, while the Star Series is made of aluminum. And the pen grip of the star series is black and transparent. Hunter and Star series pens can not only be equipped with ink absorbers, but also can be used as disposable ink bags. If you have enough money, you can try lamy2. This pen has a high position in lamy. It has a 14k gold tip, a glass fiber pen body, a piston inking and a visible ink window. But you can't use disposable ink bags. However, this point can be basically ignored, because disposable ink bags are more expensive and the cost performance is not very high. But its writing experience is absolutely first-class. Online shopping, 78-82 yuan. If you have any questions, just ask.
