Types of Pen Refills and Their Different Characteristics Pen refills are an important part of writing instruments, and different types of pen refills have their own unique characteristics and uses. Below are several common types of pen refills and their features. First, there is the water-based pen refill. This type of refill uses water-based ink, which has the following characteristics: 1. Bright colors: Water-based ink is highly pigmented and produces bright and vivid colors that are difficult to fade, resulting in clear writing or drawing effects. 2. Quick drying: Water-based ink dries quickly and does not easily smear, making it suitable for both writing and painting. 3. Environmental friendliness: Water-based ink usually does not contain harmful substances, making it environmentally friendly. Secondly, there is the oil-based pen refill. This type of refill uses oil-based ink, which has the following characteristics: 1. Strong durability: Oil-based ink has good adhesion and durability, and the written content is not easy to come off. 2. Water and moisture resistance: Oil-based ink has good water and moisture resistance, making it resistant to moisture and water damage. 3. Rich color: Oil-based ink has a rich and vibrant color that is suitable for occasions that require high saturation colors. Thirdly, there is the neutral pen refill, which has ink properties that are between water-based and oil-based. This type of refill has the following characteristics: 1. Uniform and smooth writing: The writing effect of a neutral pen is uniform and smooth, without the issue of water-based pens having gaps in writing or the excessive color of oil-based pens. 2. Wide application: Neutral pens are suitable for various writing occasions and needs, such as offices and studies. 3. Easy storage: Neutral pen refills do not easily dry out and have a long shelf life.
