At present, the most common brands listed above are: Japan’s Mary (Mary), which can be purchased almost anywhere where markers are sold. There are two types of single-head water-based pens and double-head alcohol pens. Water-based ones are cheaper and more people use them, but the effect is (..). The barrel of the double-ended alcohol pen is thinner and the two pen tips are smaller. Personally I don't like this heavy feeling either. Currently, the most popular TOUCH in South Korea is the double-ended alcohol type, which is cost-effective and is used by many people. The two pen tips are medium in size and come in many colors. When purchasing, you should try the color of the pen in person. The color sample of the pen appearance may be slightly different from the actual color. However, overall, it is more economical and affordable! SANFORD's Thunder Horse series are of very good workmanship. You can tell at a glance that most of the ones sold on the market are double-headed non-toxic oil-based ones. Personally, I feel that its two heads are a bit too extreme. The big head is very big, and the small head is only as small as a syringe pen. I don't really like this, I don't know if other people like it, the price is not particularly expensive. German Swan can also be seen in other places, as well as some other brands from Germany, South Korea, Japan, and the United States, regardless of that for the moment. Of course, there are COPIC markers from well-known brands, but these are expensive and not something that ordinary people can afford. COPIC markers can draw directly on copied drawings without dissolving copy toner. The pen barrel has two ends, one thick and one thin. Can be watered repeatedly. Newbies are advised to use domestic FANDI 4.8 yuan/piece, which is relatively cheap and suitable for familiarity with the various properties of marker pens. When you reach a certain level, you can buy Korean TOUCH 7.9/piece, which can be said to be the most cost-effective pen on the market
