The main differences in the nature of pen refills and ink lie in their materials and storage methods. Pen refills usually contain a fixed amount of ink or pigment and have a longer service life. Ink, on the other hand, is loaded into specialized ink bottles or cartridges and can be easily replaced or refilled as needed. II. Selection Guide 1. Selection based on Needs (1) Purpose: Choose the right pen refill or ink based on your needs. For example, if you need a writing tool with long-lasting durability, choose a pen refill with high durability; if you need to change ink frequently, choose a convenient cartridge or ink bottle. (2) Color: Choose the right color based on your needs. Common colors include black, blue, red, etc. Different colors of ink are suitable for different occasions and needs. (3) Brand: Choosing a product from a well-known brand can ensure the stability of quality and performance. It is recommended to choose products with a good reputation and after-sales service. 2. Pay attention to quality and performance (1) Smoothness: Choosing a pen refill or ink with good smoothness can ensure a smooth writing experience, avoiding problems such as broken lines and stuttering. (2) Dry Speed: Choosing ink with good dry speed can avoid problems such as blurry or smearing handwriting. This is especially important for users who need to write quickly or make multiple corrections on paper. (3) Lightfastness: Choosing ink with good lightfastness can ensure that the handwriting remains clear for a long time and does not fade easily. This is very important for documents or works that need to be stored for a long time.
