When we choose an eyeliner, the first thing to pay attention to is the texture of the nib. A pen with a moderately soft and hard nib is not only easy to master, but also able to draw smooth lines with ease. For beginners, choosing such a nib gives you a better grasp of the technique of eyeliner. In addition, the tip of the pen should avoid split ends to ensure that the eyeliner is drawn neatly drawn.
When it comes to water and sweat resistance, it's crucial to choose an eyeliner that performs well. This will prevent your makeup from smudging when sweating or wet, giving your makeup a longer lasting look. This eyeliner is excellent for water resistance while drying quickly, allowing you to maintain your beautiful makeup in all situations. 
Finally, consider the weight of the body when choosing an eyeliner. A pen body that is too light may be difficult for the user to control, while a pen body that is too heavy may make the hand feel tired. Therefore, when choosing an eyeliner, it is advisable to try different products to find the one that best suits your feel. The weight of this eyeliner is moderate, so it won't make you feel light and unstable, nor will you feel tired in your hands. 
To sum up, there are many aspects to consider when choosing the right eyeliner, including the texture of the nib, water and sweat resistance, and the weight of the pen. Only by considering these factors can you find the best eyeliner for yourself and make your makeup look more perfect.
In addition to the points mentioned above, you also need to pay attention to the thickness and color of the tip when choosing eyeliner. For beginners, it is advisable to choose a thinner nib, which will make it easier to master the technique of eyeliner. As you get more advanced, try a thicker tip for a more intense lash liner. In addition, the color of the eyeliner is also an important factor to consider when choosing. Choosing the right color based on your skin tone, eye color, and eye shape can better balance the overall effect of your makeup. For example, if you have rounder eyes, opt for a black or dark brown eyeliner that will create a more sculpted effect. In conclusion, there are many aspects to consider when choosing the right eyeliner, from the texture of the nib, water and sweat resistance, and the weight of the pen body to the thickness and color of the nib. Only by considering these factors can you find the best eyeliner for yourself and make your makeup look more perfect.
