Brand is very important. I recommend the Shuangyang brand Shanlianhu pen - it's very easy to use - it's a pleasure. Pay attention to the trademark - "shuang" is the traditional Chinese character for "double". You can find it at local shops that sell pens, inks, paper and inkstones, or First search online - the manufacturer has its own web page - Baidu web search, there are many kinds of pens, I personally do not recommend buying a set of pens - this is usually a gift, although it is equally easy to use, but the price is slightly higher, and it is practical Whether you buy one or several of the same pen depends on what you use the pen for. Different pens have different uses.
