A pen is a writing instrument mainly made of metal. It contains ink (mostly black or blue) through a hollow pen tube, and then writes through a duckbill pen through gravity and capillary action. It can be said that it is a writing tool of western calligraphy. Most pens can be replenished with ink. Generally speaking, vials or straws such as eye drops are used to supplement the kit.
Water-based pen: It is usually called water-based pen. Water-based pen is characterized by a spherical nib and a refill that can no longer absorb ink. After more than ten years of development, it is popular in institutions, companies and universities because of its convenience, cleanliness and fluency.
The main solvent of water-based pen is water. Common water-based pens are ballpoint pen, signature pen, plastic, brush pen and highlighter pen. Compared with oil-based pens, water-based pens are tasteless, the nib is not easy to dry, and the writing is light-resistant but not waterproof. When it comes to water, it will be rendered, and if it is accidentally dropped, it will be easy to cut off water.
If you are practicing calligraphy, it is recommended to use a slightly elastic pen, that is, a pen with a wide head, if it is an entry stage. Don't use art pens or ultra-fine pens. If the artistic pen is not used well, there will be more blocks and thinner strokes. Too thin or too sharp forehead strokes are difficult to control and press, and hard ones are not conducive to learning "calligraphy". Ordinary "writing" doesn't matter
If you have a certain foundation, you can try a gel pen and write all kinds of fonts. Various brushstrokes can also be written. Especially in winter, you can avoid the trouble of pen blocking water.
