Using high-quality pens in primary school calligraphy can help improve the quality and speed of writing. Generally speaking, a pen suitable for tracing red needed to have the following characteristics: 1. Soft and not easy to cut off water: Because it needs to be repeatedly smeared when tracing red, a good pen needs to be soft and easy to write without being easy to cut off water. This can reduce the discomfort and waste when writing. 2. Fine pen tip: Because primary school students need to repeatedly smear when tracing red, a pen with a fine pen tip can draw more delicately and improve the accuracy and effect of writing. 3. Bright colors: Because tracing red is a process of imitating writing, bright colors can help primary school students better observe and remember. Based on the above characteristics, it is recommended to use some brands of red pens such as Morning Light, Zebra, White Snow, etc. when writing calligraphy in primary schools. These brands of red tracing pens usually had rich colors and writing performance to meet the needs of primary school students. At the same time, he had to pay attention to controlling the strength and writing speed of the pen to ensure the quality and effect of the writing.
