As a masterpiece of Mitsubishi Signo series, UM- 15 1 created the 0.38 era of China gel pen. When it entered China in the late 1990s, the UM- 15 1 of 0.38 water-based ink faced the market dominated by 0.5/0.7 oil refills, which triggered a "ultra-fine" trend. The sense of use is almost impeccable. If you must say that UM- 15 1 has shortcomings, please remember to stamp it! Ink with excellent water resistance also means easy to dry, which is a contradiction that you can't have both. Baile V5
This V5, included in the "Hi-Tecpoint" series in Japan and China, is still the most slippery gel pen I have ever used, and I have no impression of it. The actual line width of the 0.5mm needle barrel pen core is 0.35mm, plus the V-type pen which claims to use up the last drop of ink and the thick straight ink bag, its writing life is probably the highest among the straight liquid gel pens, and it is conservatively estimated to be above1000 m. Smooth and labor-saving, a sharp tool for brushing questions. Zebra JJ 15
JJ 15 is probably one of the cheapest Japanese products you can buy. Cheap Japanese brands are often mistaken for fakes, leading to unsalable sales. This world of looking at faces is really desperate! The water outlet is also unambiguous. The line width of 0.5mm refill is often wider than other brands, and it is easy to obtain a certain line width change by controlling the writing speed. A pen can meet all your needs. Buy it!
