Boyfriend likes to draw and write calligraphy. What should I give her?

Boyfriend likes to draw and write calligraphy. I think you can give him a better Four Treasures of the Study in Four Treasures of the Study. They say it's best to use a lake pen for writing brushes. The ink is preferably Hui ink. Of course, you can check all these online, which is better, you can look at the price you can accept, and then give it to him if you think it makes sense. I think Four Treasures of the Study is a good choice. Of course, you can also send only one thing, such as a brush, a set of brushes, a set of large, medium and small, suitable for various occasions. Of course, you can give him something else. But I think since you mentioned that he likes painting and writing brush, I think it's better to send it to Four Treasures of the Study.
