First, the secrets of choosing a gel pen: Among a vast range of school supplies, the gel pen is favored by students due to its smooth writing experience and ease of use. However, with a multitude of brands and models available on the market, how do you choose a suitable gel pen? Here are the secrets to selecting a good gel pen.

1. Quality of the Pen Barrel: A high-quality pen barrel should be smooth in texture, comfortable to touch, and have a certain level of durability against impacts. Avoid choosing thin and lightweight barrels as they may be prone to accidents during use. 2. Type of Pen Tip: Different scenarios require different thicknesses of pen tips. For example, for exams or daily writing, a fine tip with a diameter of 0.5mm or 0.38mm is suitable; while for drawing or signing, a thicker tip may be preferred. 3. Quality of Ink: The fluidity and color of the ink are key factors in choosing a gel pen. High-quality ink should flow smoothly and have a bright and long-lasting color. 4. Brand Reputation: Choose a well-known brand for your gel pens, such as Muji, Zebra, or other reputable brands, as their products are generally more reliable in quality. Second, techniques for using a gel pen: 1. Holding the Pen: Hold the pen lightly and comfortably at the back of the barrel to avoid overexerting your hand muscles during writing. 2. Writing Pressure: Control your writing pressure to prevent excessive ink flow or paper damage due to excessive force. 3. Continuous Writing: Take breaks to rest your hand muscles when writing continuously for long periods to prevent hand fatigue.

1. Regular Cleaning: If you find that the ink flow is not smooth, try cleaning the tip with water but be careful not to let water enter the inside of the barrel. 2. Avoid High Temperatures and Humidity: Store your gel pen in a cool, dry place out of direct sunlight and high humidity to prevent ink drying or mold growth inside the pen due to high temperature or dampness conditions respectively (this is also true for other types of pens). 3. Avoid Abrasion: Avoid rubbing your gel pen against hard objects to prevent tip wear that can lead to poor writing performance (or in the case of broken or rough-feeling nibs).
