👉 The stylus fluid, also known as ink or marker fluid, is a specialized liquid that serves as the medium for transferring ink from a stylus or pen to a surface, whether it be paper, glass, or digital display. This fluid is carefully formulated to ensure optimal performance and longevity of the writing tool. It typically balances viscosity, allowing for smooth and precise ink flow, while also maintaining a stable consistency that resists drying out or clogging. Additionally, the fluid often contains additives that enhance its adhesion to surfaces and prevent smudging or bleeding. The composition of the stylus fluid can vary depending on the intended use, such as fine line work, bold outlines, or digital applications, each requiring a unique blend of properties to achieve the desired results.
